One of the things I do like in season 6 is Clem. Angel has had various friendly demons for a while, but I think Clem is the first real friendly demon we get on Buffy.
The avatar I have had and never changed since I joined shows that Clem is my kind of person. Opportunist? He gets Spikes crypt when Spike goes away. Sociable? He and Dawn get along great and Buffy thought enough of him to leave Dawn with him. (Of course, she did the same with Spike - maybe it's the crypt.) Fun-loving? He managed to scare the potentials in the demon bar. Healthy? He is a junk food junkie just like me. (I have taken the computer programmer's vow - I will eat nothing green unless it is meat.)
And his eight episodes were played by James C, Leary who trained as an engineer (just like me) and is now working as a game designer.
