I like Gerry he's quite funny, love the way he handles his arguments with the witches, he just uses sarcasm and makes them look stupid. Good on him.
As for him thinkin he's better because of his education whats wrong with that? Being intelligent is a good trait to have and so he should be proud of it. He's not sneaky at all, he just makes it clear how he feels about the witches and good on him for that.
Go Gerry
