They don't seem to have a fully formed personality between them. When they're trying to be funny, I don't find their tweedle dumb and tweedle dumber act engaging or endearing.

If they showed some growth or maturity in the house, made friendships separately, even had a showmance with Hazel (but they're too young mentallity and physically for that), there would be some point to having them as HMs. But at this stage they are incapable of any real development which means they are a waste of a HM. Which is wrong. They should never have been put in there.
