Well fuck you too causality!

So I followed Brian into an alley and I figured this would be it. I'd murderize the bastard and be on to my next assignment. Obviously it didn't go like that. Brian puts his hand on the wall and a Door appears. Yeah... A Door as in To The Empty City. The bastard summoned a Door! He opened it and walked through and then it disappeared instantly. Do I just attract crazy events or something?
