Frankly, Shane (David Alpay) was getting on our last nerve until he looked so broken and defeated in The Vampire Diaries Season 4, Episode 14, “Down the Rabbit Hole.” His wife came to him in a vision — we think — and the professor just seemed so crushed that he’d never truly see her again.

Cut to a sneak peek for Season 4, Episode 15, “Stand by Me,” and Shane is ambulatory and creepily happy once again. Silas has risen, and the PhD still wants to bring back the dead.

No wonder Bonnie (Kat Graham) needs a new mentor. TV Guide reports that Cynthia Addai-Robinson (Spartacus: War of the Damnedhas been cast as Aja, and she’s taking over the job.

Unlike Shane, Aja is a skilled witch — a friend of Abby Bennett’s — who wants to help Bonnie get her use of Expression under control.

Great! The less time Bon-Bon spends alone with Shane, the better. And if Aja knows any spells for raising the dead, Jeremy (Steven R. McQueen) could definitely use one!
