Blue was still smiling as she looked up at him, though it might have been just at touch shyer than Blue's grins usually looked. She had been content to stop there, having already gotten far more than she had imagined she would, but if he was leanining in for the reasons she guessed he was...

Taking a chance, she let her fingers crest over that spot one more time. It was a good scratching, and this time Blue spoke up as she did it, keeping her voice hushed as if it were all supposed to be a secret. Which maybe it was.

"I was curious if this spot would feel nice to other Charizards too. Sienna really likes it, but she's just one of you... I don't know any others well enough to ask."

The trainer slowly drew her fingers away after a few last scritches, and she moved her hand to shyly push back a bit of her hair behind her ear. She glanced back up at him, her smile somewhat apologetic now. "... So thank you for indulging me. I'm sorry I didn't ask you proper."
