- Klaus mentioned that some of the unsuccessful hybrids died from blood loss, and others died because he killed them. However, it's unknown from which cause each of the individual members of Paige's Pack died.
- Hayley is somewhat unique among hybrids, as she is now the only hybrid who was sired by Hope Mikaelson, who is the world's only living (not undead) hybrid. The first hybrid to be sired by Hope was Dwayne, who was sired while Hope was still in utero, but he was killed by Tyler just minutes after completing his transition.
- It has also been revealed that Hayley is also the only vampiric being whose life is not dependent on the survival of the Original Vampires due to the vampiric sireline link. However, it is unknown if this means her life is tied to Hope's, as Hope is Hayley's sire, though it seems likely that this is the case.
- There are currently a single being left alive for each type of hybrid.
