Pollux: checks wallet for an ID, watches the area closely for anyone looking for something. He hangs onto it if he can’t find the owner right away, and he passively searches for them then.
Cyrus: Freaks out a little bit, tries to find the owner for some time but eventually gives up. He never spends the money though because he’d feel too guilty.
Abraxas: Takes the wallet, gives a half-assed effort to find the owner, and takes their cash and any gift cards. When and if he returns it, he just says those were gone already.
