|“||Aiden, I've kinda been on my own my whole life. And then suddenly everything was different because of you. You are my pack, you and Marcel and Davina. And yeah I'd die for you because I don't think I can go back to how it was before.||”|
— Josh to Aiden in Night Has A Thousand Eyes
Throughout The Originals Series
They first met in the episode Live and Let Die, when Josh is at Marcel's loft with the rest of the new vampires, checking his phone. Marcel asks him about any prospects and Josh informs him that there is this one guy he's been messaging with and that he really likes him. When Marcel asks what the problem is, Josh then expresses doubt about having any kind of normal relationship on account of his need of blood to survive. Before the conversation can go any further, someone is thrown through the window. The loft is suddenly swarmed by werewolves wearing Moonlight Rings. The leader of the wolves, Aiden tells Marcel that the deal of the vampires staying out of the Quarter is over and that the vampires must leave New Orleans entirely. To prove his point, he has one of the other werewolves bite a vampire. When another goes for Josh, he calls them off and warns Marcel that they need to be gone when they come back, because he won't call them off next time.
At the end of the episode, Josh is at Bywater Tavern, glancing at his phone and looking a little nervous, when Aiden comes in and it's revealed that he is the guy Josh has been messaging on the dating app. After a brief conversation, the two decide to pretend they're not at war for the night and just be themselves.
In the episode Chasing the Devil’s Tail, Josh is at Marcel's loft with Aiden, Hayley and Marcel as they all outline a plan to take out Finn who is possessing the witch Vincent Griffith. Cami soon shows up with a box full of Dark Objects that are able to take down a witch. Josh makes a joke of it, "Sweet it's a big box of dusty old junk. We're saved", which Aiden laughs at.
Josh is later seen at St. Anne's Church with the others as Aiden lures Finn there. As Aiden goes to snuff out all the candles, Josh follows him and says he understands that Aiden would much rather be doing push-ups or drinking with his bros, but Aiden is quick to point out that this isn't so bad, earning a smile from Josh.
When Aiden is later thrown through the church by Finn, knocking himself unconscious, Josh immediately rushes to his side before standing up to defend himself. Unfortunately, he doesn't get the chance as Finn easily snaps his neck with his magic.
In The Brothers That Care Forgot, Davina is venting to Josh about how she feels like a failure while throwing darts at a dartboard. Josh points out that she's not the only one, citing how every werewolf in the city wants to kill him... except one, but that has its own problems, a whole Romeo and Romeo thing. Davina, clearly interested, asks about this Romeo and Josh shows her a picture of him. Davina says that he's pretty hot and is totally worth the drama, telling him to invite Aiden over, wanting to meet him. After calling Aiden, Josh leads him into the loft where some music is playing. When Aiden remarks about Davina's great taste in music, Josh quickly corrects him by saying that he picked it out and that Davina wanted Puccini.
They introduce themselves, with Aiden cracking a dumb joke about how he's a werewolf betrayer. Davina recovers quickly and says she's going to go order some Thai food, leaving Josh and Aiden alone. While Davina's out of the room, Josh asks if everything's alright with the pack sensing some discomfort after the "werewolf traitor" comment. Aiden explains the situation and Josh expresses his confidence in him before the two share their first kiss.
In Gonna Set Your Flag On Fire, Hayley arranges a meeting between the wolves and vampires, including the involvement of Josh and Aiden. While gathered in the building, Finn performs an enclosure spell that traps them. As the right arm of both leaders of the respective factions, the two guys scour the area to find a loophole to the spell. While they are on a terrace, Josh kisses him but when Aiden dodges, Josh asks him if he is ashamed, and for the first time refers to Aiden as "his boyfriend". Aiden then tells him that it's cool that the vampires accept them, but the wolves are harder about the issue, as they still hold grudges for centuries when vampires killed and cursed them. In fact, the wolves don't know of their relationship. During the heated discussion, Josh is victim to another of Finn's hexes. He can only seem to focus on Aiden's pulse. The young vampire, at this point, leaves the room hurriedly to go seek help from Marcel, leaving Aiden seemingly worried. It is revealed by Josh that the spell Finn cast is causing the imprisoned vampires to gain an uncontrollable hunger for blood. Later, Aiden tries to break apart a fight between a hungry vampire and an agitated werewolf, but is wounded and severely cut in the process. The exposed blood causes a couple of the vampires to swarm Aiden, ready to feed, but Josh snaps one of their necks and pulls off the other. The hunger for blood puts a strain on Josh, with him seen staring at Aiden hungrily. Klaus intervenes between the two, preventing Josh from attacking Aiden. Seconds after Davina and Kol interrupt the enclosure spell, Aiden and Josh exchanged a meaningful look
In Sanctuary, Aiden texts Davina to tell her that Josh and Marcel are missing. Aiden and Davina then arrive at Kol's Playhouse, so that Kol can perform a locator spell to find Josh and Marcel using Josh's personal object which he left at Aiden's, resulting in a snarky comment from Kol. As soon as they get the information through the spell, they go to the place to save the vampires. Aiden and Davina sneak in through the back of the store to save Josh but Finn wakes up all of the vampire, who are still hungry; Aiden and Davina try to escape but Josh blocks off the way and tries to bite Aiden but he snaps Josh's neck with a regretful look before he carries him out with Davina behind them.

- Josh (to Marcel about Aiden): "There is this one guy. We’ve only been messaging so far, but I think I like him. Like, really like him."
- Josh (to Aiden): "We could just, I don’t know… be ourselves? P.S. These pictures don't really do you justice. You're way hotter in person, you know, when you're not murdering people."
- Josh (to Aiden): "You know, those people look up to you. I mean trust me I've seen you in action. You're a badass! And hey, look, if you, uh, get nervous, or, like, need a vote of confidence or whatever? Just remember that, uh, I think you're pretty amazing."
- Aiden: "We are going to Hell for this."
- Josh: (laughs) "Yeah, you get used to it. Hey, I know this probably isn't your ideal Friday night. I'm sure you'd rather be like doing pushups or drinking beers with your bros or whatever."
- Aiden: "Eh, it's not so bad."
- Aiden: "Aw, come on. Someone might come up."
- Josh: "So? I don't really care if somebody sees me making out with my boyfriend. And, I totally just called you my boyfriend."
- Aiden: "Yep!"
- Josh: "So, that happened."
- Aiden: "Look, the wolves don't know about us yet."
- Josh: "Ok, Aiden, please tell me that I did not get murdered and come back from the dead just to get shoved back into the closet."
- Aiden: "No! No, it's not that. It's just... you're a vampire. And, you know, it's great that your friends are cool with this, but it's different for the wolves. I mean, you don't know how Marcel and his vampires made us suffer."
- 'Josh: "No, you're right. I don't. Because I had nothing to do with what happened back then."
- Aiden: "Yeah, well, trust me. You were the bad guys."
- Josh: "Thanks for coming. Look, I know I owe you a massive...apology."
- Aiden: "You scared the hell out of me."
- Josh: "I know, and I'm sorry. I just.."
- Aiden: "Look, um... Hayley and Jackson are getting married today. Quarter's gonna be packed with wolves. 'Kay, and after this wedding? Our whole pack will inherit Hayley's control of her wolf form! That means werewolves will be able to turn at will-- we'll be that much more deadly to vampires. To you." (Josh looks at him with a hurt expression) "I... think we need a time-out."
- Josh: "Whoa, whoa! I'm sorry, is this the World's Worst Breakup Speech? Because if so, just say it like it is-- you wanna call things off because it would look bad for the Werewolf VP to be dating... me."
- Aiden: "No! Dating me puts a target on your back! I'm just trying to keep you safe!"
- Josh: "Okay, you know what? I can't remember the last time I was safe."
- Aiden: "We should probably get up now."
- Josh: "Yeah, definitely. Hundred percent."
- Aiden: "So it's settled then, uh?"
- Josh: "I am basically already out of the door!"
- Aiden: "Oh yeah?"
- Josh: "Or we could stay in bed all day long. Yeah, some Netflix, Chinese food... probably some other stuff."
- Aiden: "Josh, uhm, I'm so sorry for all of this."
- Josh: "Yeah. Me too. I mean, mainly because if Klaus hurts you, I'm gonna seek vengeance psycho ninja style and I think we both know how that's gonna go..."
- Aiden: "Josh, I love you."
- Josh: "Oh, no... What are you gonna do?"
- Aiden: "Look, here's the thing-- I am who I am, okay? Loyalty is in my DNA. But, I can't live with myself if I'm someone who's spying for Klaus, because I'm not cut out to be a double agent. So, I'm gonna tell Jackson everything."
- Josh: "What, because it's so much better to be killed by Jackson than Klaus? And even if he doesn't kill you, then what?"
- Aiden: "Then meet me in two hours. Let's get out of here and finally start our life together."
- Josh: "Wow. You really want to just go? With me?"
- Aiden: "Like I said, I am who I am. I'm a pack guy, and you are my pack now."
- Josh: "Wow, leave. Okay, um, wow. I mean, I'm finally pronouncing all the street names right. And, I know I did die here and all, but well, this was the first place I ever felt like myself."
- Aiden: "I know this is all really fast. But, if you want this, I'll see you in two hours."
- Josh: "Yes. I'll be there."
- Aiden: "Good."
- Josh: "Aiden? I love you, too."
