You're back at the mansion, in the Estate Grounds, you can talk to several students, and to Jubilee as well. But before starting the next mission, there are some things to do (see below). When you're done, go to the subbasement, here you can talk to Toad if you want, but anyway head to the Danger Room. When you're done with it, go talk to Beast to do the Juggernaut Flashback. When you're done with the Flashback, head to the War Room to start the next mission.
