Oh boy, Buffy is going to find out what a great guy Liam was (is). He lets someone else support him while he does whatever he wants, AND expects her to never question him. I like how comparisons between Angel and Spike pop up in Buffy's mind (unwanted, but inevitable). She needs to see, on a day-to-day basis, that Angel is a self-centered user.
Can't wait to find out the backstory about how he came back human, why he showed up exactly where she was, etc.
