Continuity mistake: This is subtle and hard to notice. When the teacher is giving a lecture in the beginning, she says "Ok, so talk to me people " and starts to turn and walk to her right. When the camera cuts, she starts to turn and walk to her right a second time. It goes by fast, so it's kinda hard to see.

The same girl in light blue can also be seen in several different shots, in the crowd listening to Cordelia and walking around as Buffy talks to Willow and Xander.
Chosen answer: Angel is saying that he is still jealous and Buffy recognizes that this is his way of saying he wishes that they could be together. That is why they both smile.
