"She embarrased me" sentence seems like Iain is referring to when he went to the writers and asked for more scenes, probably he told her after and she teased him.
Because, just my opinion, if he were referring to what she told in the interview (a few moments ago), he would say something like “she is embarrassing me”.
But then again, it’s my opinion and I might be wrong.
I actually think she was joking around, and that he didn’t actually ask. It would be nice if he did, but to me it seems as if she’s just messing with him to embarrass him.
If I remember rightly, he did say “she’s embarrassing me. She embarrassed me”, referring to her fooling around. The whole quote isn’t on the giff.
