Well, of course he can't stay like this! It ain't exactly his natural state of being, and like Fagin was going to give a rat's arse about his being light that month on account of being turned into a frog. He gives a very annoyed look up at Girl - impressive, for a frog - as if he were blaming her for most of this.

Maybe he was. Though, as for pissing off a witch...? Well, Nancy was still mighty annoyed with him, but she wasn't one for turning people into frogs. She wouldn't do it, she knew Fagin wanted him working.
