get spoiled before?
knew Raven would die as it was given away in the trailers (whyd they do that?)
also knew thered be no Wolverine cameo as Kinsburg said so at the premiere (not that was expecting a cameo as be abit silly coming back after the send off in Logan)
didn't know if any of the others would die but then knew they wouldn't ruin the DOFP ending (where we see Jean, Scott, Strom, Hank, Prof X) so only Magneto, QS etc was uncertain..
