"Any time, I told Martha about you and she was like my mum about it."
Completely fine and because she wasn't his mum, interested but not like 'no boys in your room' interested so he figured having Charlie over was more than okay. Plus he wanted to.
"It's a bit confusing in my head at the moment," he admitted with a laugh, then nodded at the offer of a drink. "There's snacks too."
