Reptile Boy was an ok episode, highlighted by Willow's outburst putting Angel and Giles in their place. With all the pressure Giles puts on Buffy and Angel blowing Buffy off, it's nice that Willow is the voice of reason in this situation. I hope we get a Willow episode soon because it feels like she's being sidelined so far. Heck, if there is an apt comparison, I would say she's the current season Cisco (Flash) so far, the techie who needs a lot more to do.
I can actually relate to the whole uncomfort thing at the house party. I remember when I transferred to the 4 year college and they would have house parties, they were some of the most uncomfortable social gatherings I've been a part of. I need to work on being more social, but you can't be social at a house party, not when everyone is getting drunk and they will forget you the next day.
