So Elliot is going to be on team "Yell at the mutineers for being morons."

Because yes, despite the fact that he complains about the Initiative a lot? Elliot does realize that they understand more about how all this stuff works and the state of their world than the rest of them do. So he thinks mutiny is pretty stupid, because if you have a problem with the Initiative, you should just try to let them know and not make a stupid mess. Just keep trying until they listen, don't potentially endanger people, wow.

He's completely willing confront them in any means necessary to get his point across, whether it be in a slot or just standing somewhere and yelling.
