She became close with his son as well, yeah. Buck likes her, and calls her "Pointy Mom". As I said in her character sheet, 'Buck Dewey took to Pearl quite easily; she was kind to him, albeit rather awkward.' When she broke up with his dad, though, Buck started avoiding her. She doesn't really understand human relationships, so she doesn't understand how much she hurt him. :)

I'll post what I've done so far in a bit, I've nearly finished coloring her... whoops.
