Harry's answer is actually more than he expects. It's not exactly no. It's not some indication that Harry doesn't have interest. He's not aware of the exact number of years between them but it's a lot. Eggsy doesn't really care about things like that. Harry's well fit, and it's...more than that, but he's not really enough of a navel gazer to have that sorted in his head yet.

"Ain't like I'm gonna tell no one," he says, shrugging, trying to play this as cool as he does most things. He's half-successful at it, but his eyes are too busy searching Harry's face to sell it entirely.
