Bobby was in as soon as he heard they were going to Gotham. Despite the recent weirdness between them, Jubilee was like a little sister to him, and the hurricane had been -- in typical hurricane fashion -- bad news for everyone involved.
He worked with some students and staff to fill a couple of coolers full of food for the trip. Some of it would be for the X-Men, as the help-and-rescue effort was bound to work up an appetite, but a majority of the food would be for the people who needed it.
Once that was done, he suited up and helped load the coolers into the van. The ride was a grim one, and while Bobby wanted to lighten the mood, he didn't dare do anything to get on Logan's nerves.
Once they emerged from the van in Gotham, Iceman joined Colossus, Rogue, and the others in awaiting orders. He could already tell he was probably going to be put to use in creating ice barriers to fortify structures long enough to get people out of them.
