Young Love, Shattered: Happy TV Engagements That Ended in Total Disaster

Lovebirds: Daniel (Joshua Bowman) and Emily (Emily VanCamp)
Show: Revenge
How it went wrong: In the middle of their engagement party, his best friend gets murdered in cold blood, and he’s caught holding the smoking gun — literally (well, more or less). He gets sent off to prison and is promptly beaten within an inch of his life. She stays loyally by his side like any good fiance would. Oh, except the only reason she’s with him in the first place is so she can destroy his entire family for arranging her father’s murder. So there’s that.
