Class is in session on The Vampire Diaries — except this is one awkward lesson.

On the Season 6 premiere, Professor Saltzman (Matt Davis) is at the head of the class, while Elena (Nina Dobrev) hides behind her book and Liv (Penelope Mitchell) obnoxiously laughs at the day's topic: the occult as it pertains to resurrection.

"Is there something funny, Liv?" Alaric asks.

"More like, ironic," she snarks back. (We have to give her that one considering the events of the Season 5 finale.)

But that's not our favorite part of sneak peek. Before the end, Tyler (Michael Trevino) — muscle tee and all — pops into class, sits down and banters with the blonde witch. Do we sense some major post-hook-up tension? Will that back-and-forth will lead to something in the bedroom? And side note: How great is it to have Tyler back in school? For a second, it feels like old-school Mystic Falls High!
