[His displeasure wasn't exactly hard to ignore, and Elphaba knew as soon as she did it it would piss him off. But, she wasn't in the mood to argue her actions with him; she was allowed to kiss whoever she liked. (Although that saucy lip action is reserved only for Piccolo, no worries)

Once they were outside the room, she closed the door glanced up at him. She hated making him angry, even when she was well within her rights]

Hey..thank you for helping him. I know you two loathe each other, but it meant a lot to me that you did

[She had to stop herself saying 'he means a lot to me'..That would have opened a can of worms..]
