Damon has officially crossed the line. In the last episode of “The Vampire Diaries,” Matt found the body Damon abandoned on the road — the body of Tyler Lockwood. It seems like his death will force Stefan make a painful decision in Season 8, episode 5.

“Spiraling down a dangerous path of self-destruction, Damon’s (Ian Somerhalder) latest actions prove he may be beyond the point of return,” the synopsis reads. “Unwilling to give up on his brother, Stefan (Paul Wesley) is forced to make a gut-wrenching decision that threatens to change their relationship forever.”

So what’s this “gut-wrenching decision” that Stefan must make? According to the promo video above, Stefan wants to “put him down.” He has to stop his brother somehow. He was hoping to save Damon from the sirens’ control, but if all of their loved ones are in danger, Stefan might view Damon’s return to a coffin as the only option.
