@ultraleaf I feel like some of the knives were pointed at them and the rest towards the door. She said for them to be guided, so I kinda took it like the knives were simply pointing to the exit as said guides. When they still refused to go after that, then she just force pushed them out. Honestly, she gave them a lot of chances to either behave or get out, and even after the countdown she gave the one more chance. Pity for them, because that place seems like a great place to relax in after a long hard day of fighting.
Edit: On second thought, I think those knives were actually passing them by, as in she threw out the knives as a threat and purposely missed the mercs with the knives. It's just the camera angle made it look odd.
