i just think personally jerry is a bad guy he just wanted to put the trench coat in his closet for a few months. he also treats his poor uncle leo very badly.
I wouldn't put some dudes coat in my closet. If your closet is so full you can't fit 1 item, you should probably get rid of some stuff.
Jerry never treated Leo badly. He stayed and talked when he wasn't busy and had to leave him when he was busy, like any other normal person. He also paid him handsomely for the watch he got for free.
Leo stole money from his sister and tried stealing books from the book store.
