In the pictures we can see that Professor Shane (David Alpay) is already heavily involved with the story and the gang. Not only has Bonnie clearly taken a liking to him, but Damon is also spending time with the witchcraft expert.

The episode description for “We All Go a Little Mad Sometimes” reads:

ELENA’S NEW NIGHTMARE – Terrifying hallucinations leave Elena (Nina Dobrev) shaken and confused, causing her to make a dangerous mistake. After giving Stefan (Paul Wesley) some very disturbing news about Elena, Klaus (Joseph Morgan) takes matters into his own hands. Professor Shane (guest star David Alpay) reveals a story of ancient witchcraft to Damon (Ian Somerhalder) and Bonnie (Kat Graham). With help from Klaus and Stefan, Jeremy (Steven R. McQueen) begins a new chapter in his life. Finally, Elena makes a painful personal confession to Stefan, and Matt (Zach Roerig) gives Damon startling new information about Professor Shane.

Are you looking forward to potentially seeing Bonnie get involved with Shane, or do you think she should try to reconnect with Jeremy?

Don’t forget that The Vampire Diaries returns tomorrow night with “The Five,” in which we’ll see a flashback to the 12th century, revealing a surprising connection between Klaus, Elijah, Rebekah and the mysterious Five. The episode airs on The CW at 8/7c.
