The home was first seen in The Sacrifice, when Jonas performed a "shadow spell" to locate Elena Gilbert, who happened to be in Richmond with Rose-Marie in order to seek out information about Klaus. At the end of the episode, Elijah told Jonas that Elena needed to be kept safe, which is why he left her in the care of Damon and Stefan Salvatore.
In By the Light of the Moon, Bonnie came to the Martin's house to apologize to Luka for almost killing him when she channeled his power to break the seal on the tomb. He let her in and showed her the grimoires they possessed, as his dad, Jonas, was obsessed with collecting them.
- The room of the Martin House that was shown was the same set as the room in the Lockwood Mansion seen in Masquerade when the gang trapped Katherine there to kill her.
