[@Lugubrious] The survivors have all gone with Jack. They're waiting by the elevator already - or should be - while Cian and Lauren wait for the battery to get there so they can retrieve Luke. The whole point of zapping the poor guy was so that the lift would have enough temporary power to take the survivors up along with Jack and then let the rest of the students go up once the battery was installed. They're not all in one group.

From the looks of the post it implied that they had kinda stuck around to watch Luke get barbecued which isn't really the case.
