You should talk to Sparta about it too since he actually saw it all, but the way I know it . . . Haunted took someone from each team and paired them up to make them scare the teams out of a mansion. She gave us all the ability to make illusions, and if we failed someone else on our team would be killed.
I ran into a kid that got assigned to scare our teams and fucking gave him the knock that we used to get through the door. Everyone on Hydra knows it, so they'd have listened to any message! I was fucking handing them the way to protect their teammates! But it turned out he got teamed up with that Canis fuck, and he decided not to fucking use it.
