Matt Donovan will be back to Mystic Falls and get involved in all the drama surrounding his supernatural friends in this Friday's episode of The Vampire Diaries. Rumours are rife that he is related to Sybil, the new big bad of the season, as the brains behind the show revealed in an earlier interview that Matt also has a supernatural connection.

Elsewhere in An Eternity of Misery, viewers will see Damon heading to Texas to find a mysterious artifact, and he will have a violent run-in with Peter Maxwell. Stefan and Enzo will try to find more about Sybil's past and "Matt returns to the fray after his past and present collide in an unexpected way," the official synopsis teases. The episode will also feature Candice King's Caroline.

The Vampire Diaries airs Fridays on the CW.
