If you haven't been watching "The Carrie Diaries" wildly underrated first season, you're missing out -- and this clip is the best evidence of that. In last week's episode, Sebastian (Austin Butler) and Carrie (AnnaSophia Robb) broke up, again, as she desperately tried to include him in her glamorous Manhattan world.

But, in typical high school fashion, these two can't stay apart for long. Plus... it's prom time! Sebastian visits Carrie at home, thanks to a little help from Dorit and her guy, Miller. Their totally swoon-worthy reunion is one of our all-time favorite scenes from the show -- Carrie even tells Sebastian those three little words she spend all of last week's episode struggling to say!

Zap2it has an exclusive first look at Sebastian and Carrie's honest and romantic conversation, which showrunner Amy B. Harris tells us is one of the scenes she's most proud of writing.Let's just say it totally landed Sebastian on our list of TV's most awesome first boyfriends.

Unfortunately, before the episode was over, we had to scratch Sebastian off that list.
