Yes, I re-watched the whole hospital scene, and I think it makes perfect sense. There IS something there, everyone knows it, but it's still Barney! I think they did a great job of setting up a foundation for them to be together next season, but still have plenty of room for growth.

That was my initial thought, too. I think I've just been at my college too long, where professors only teach one class! In that situation, the professors get to know everyone, even in the big classes. I forget that that's unusual!

YES! I loved those kind of happy scenes. :)
