I'm surprised Elise didn't get angry at Izumi.

She was distracted by her headache, and the stuff Izumi did wasn't that aggravating, to be honest. There were only two things she could have been angry about (the informing and the tub shove); in the former case she found the information more useful, and in the latter case there was a reaction, but it wasn't as severe since she did want to get clean anyway.
