"Glee" delivered one bombshell after another on a sexually charged Valentine's Day episode. Finn's abrupt kiss with Emma seemed to send her into a tailspin worse than the one she was already in. Wedding preparations by herself were already taking their toll, but this proved to be too much. So much so that she stood Will up at the altar, going all runaway bride on him.

Oddly enough, the reception went on without the happy couple. And as the night wore on, everybody -- and we do mean everybody -- started hooking up. After all, all the graduates were back for the wedding, so it was a smorgasboard of young, hormonal teenagers.

Finn and Rachel hooked up, Artie hooked up with Ali Stroker ("The Glee Project" Season 2 runner-up), Kurt and Blaine reconnected and -- in a huge surprise -- Santana hooked up with Quinn. Marley and Jake made it into a hotel room, but she wasn't ready and he respected that about her.

But it wasn't all fun and games, as Rachel found out later. The episode ended with her back in New York and staring at a pregnancy test. While the results weren't given, it seemed pretty obvious she was pregnant, which could destroy her aspirations at NYADA and beyond.

Keep up with all the teen angst and drama of "Glee," Thursdays at 9 p.m. EST on Fox.
