What the hell...
Ok so I got my two helpers to watch the other two exits. Guess what happens?
None of us see him leave and yet again he appears and goes inside without any of us seeing him leave. How the fuck is he doing this?
Wait the roof? Is there roof access? Oh god that's probably it!
I'm going to move to the roof so I can watch the front of the building and the roof.
I got you now.
