It's most likely Christopher was indeed going on and on about it and whilst she raised her voice at him, he then did so and spoke to her in a patronising manner (hence her saying "don't talk to me like that").

This is the guy that was being called wasp in week one and who Tamara described as "so annoying" all the way back then.

But he's got a halo over his head and amnesty international have got behind him.
