With Willow wrapped up in her own pain and misery, Xander's lost the one sounding board he had. He's in turmoil. His concerns about Bonnie and Buffy and his own precarious position in his own life seem insurmountable. It feels like something is going to blow up in his face any second.

In all the angst, the idea of Clem tutoring Bonnie on all things human gave me a grin. I'm thinking copious amounts of snack foods and crap television. It's great training for life with Xander and Spike!
