What can we expect in tonight's episode?

Season 5, episode 4 is titled "For Whom the Bell Tolls," and airs on the CW Thursday, October 24, at 8 p.m. (EDT).

The official synopsis for "For Whom the Bell Tolls:" "REMEMBRANCE DAY - While Mystic Falls observes its traditional Remembrance Day to honor the dead, Damon (Ian Somerhalder) and Elena (Nina Dobrev) try to help Stefan (Paul Wesley) through a confusing time, a task that ends up taking Elena on an emotional journey of her own. A worried Matt (Zach Roerig) tries to figure out the reason behind his mysterious blackouts, and Caroline (Candice Accola) makes an effort to get to know Jesse (guest star Kendrick Sampson) better. Jeremy (Steven R. McQueen) makes a startling confession that hits Damon hard. Finally, Dr. Maxfield (guest star Rick Cosnett) puts a plan in motion that will change everything. Kat Graham also stars."

The biggest spoiler of the episode: Stefan doesn't remember Elena.

Stefan lost his memory after his summer submerged in water. In promo clips revealed by the CW, Damon doesn't remind Stefan who Elena is. We can only guess Damon is still jealous of Elena's former relationship with his younger brother.

In the promo clip, Damon is having a drink with Stefan but doesn't say anything about Elena.

Stefan asks for her name, "Remind me of your name again?"

"You never told him about me?" Elena asks Damon.

A love triangle is forming with Elena and Stefan getting close, Christian Today reports.

The sneak peak video shows Elena and Stefan walking by the lake. Stefan tells Elena, "You're pretty. Smart. How do I not remember you?"

Tonight's episode will show how the three characters' relationship develops, and we think some real drama is about to unfold.
