Cathy and Jon are very dynamic together. They literally go around town on wheels. I haven't done a Cathy-on-rollerblades comic in a while. I'll do one now.
@Laura Cushing I've never seen a friendship like it anywhere in fiction, so I invented it from scratch! They took to it naturally. Cathy will absolutely be friendly with anyone who puts up with her, and Jon is a softie if he doesn't feel threatened.
