She reaffirmed it, in her mannerism, in her voice. 
A part of Tyler wanted to jump just because Dani didn't want him too, a part of him just wanted to see what he could do and lastly a part of him wanted to do an ordinary boring jump and realise this was all a bad trip or concussion.

He felt that she was talking to him like some sort of child or mental patient. He felt the eyes of all of the others watching and waiting. 
He couldn't be here, the image he built for himself was shattered and he didn't want to face the embarrassment of seeing these people any more.
