[It's not quite like it sounds and he probably should have phrased it better? He's just glad he wasn't eating or drinking anything when she says the word 'dominatrix' because she is fourteen and fourteen year olds shouldn't even know the meaning of that word. He is inwardly kicking himself for not phrasing it differently to give her context.]
It wasn't like that at all, but I'm glad to hear it. I don't hold it against you. [Frankly he was over it with the other version of her, too. He really has no right to hold things against people considering some of the things he's done.]
