They had the main couple hug and give an ILY at the end of the episode(very dramatically, I might add...his little speech still gets to me to this day). They did kiss earlier in the episode, but it was more of a goodbye kiss since they thought they'd never see each other again.

I guess it was just done in a way that you felt they were back together now--like they were so relieved to be together again and the worst was over. That's how I took it at the time, anyway, and I was actually surprised when it showed him working to win her back in the next season premiere. I made sense, I guess, since they had a ton of stuff to work through that didn't just go away because the obstacles were gone. Of course, it kind of feels like this show is having Stefan/Elena sort out their problems now, instead of after they reunite.

It's kind of a delima, isn't it. On the one hand, part of me wants them to save the kiss for the big reunion, because it would be that much more powerful. On the other hand, there's always a chance we won't have a full-blown reunion, and I don't want us to go an entire season without an S/E kiss. Keeping that in mind, Julie's 'lots of kissing' and 'making up for lost time' quotes make it sound like at least some of those kisses are going to be S/E, and I'm certainly not going to complain about it.
