If Pascal was going to get upset, he'd do it after because in the end he was still just an eighteen year old. He tried to keep his cool as the woman in front of him appeared as more of a child than anything else. She didn't seem to know what to say and that said nothing good to him. When her lips suddenly fell into an 'oh god' he thought she was suddenly going to run away from him but instead what appeared before him was like a grade school child, trying to confess but not having the words to properly do so. She liked him, not like a friend but more. She may as well have just said she like liked him, it would have been more fitting to the situation.
"I did say I'd do anything you wanted," he said, something of a sly expression over his face. Drop his pants? If that was her command then so be it. How else did you solve problems these days? Pascal could only think of one.
