Pea asked for my address for a card as well. Never gave it to him. It felt like a trap, and I think it probably was, or else would have become one.
Pea tended to go pretty intensely back and forth on how he felt about people (or at least, he seemed to about me, and I remember PeterMackenzie saying something very similar about how Pea related to him), and when he decided he wanted to attack, he was vicious, mean, vindictive, and had a real lack of proportion/boundaries.
He wasn't physically dangerous, no, but IIRC he was pretty outrageous with relational aggression.
