If they decide to continue to stay in contact and see each other after tonight, hopefully he'll learn that she doesn't care. So far his guise of confidence has held because Carol is assuming that he has more experience (both in number of times and regularity) than her. Not that she's any kind of blushing near-virgin here, but she always prioritizes work over personal fun. Any kind of nerves she may have noticed she assumed where because of him taking someone with powers to bed.

"Fine by me." Any pace is fine - one of them will probably change it anyway - she's just so anxious to start.
