At 31:10 Arturo and Quinn are leaving campaign headquarters to get into a limo when an assassination attempt is made. The campaign manager, Danny Eisenbach is first helping to rush Arturo into the limo for safety; camera angle changes to Quinn with the cops having the assassin against the building; the Campaign Manager is now moving aimlessly near the building and quite a bit behind Quinn as if the actor, Robert Curtis Brown is unsure of where he's supposed to be in this scene.
When Quinn opens the vortex at the end, the door behind Arturo keeps opening and closing between cuts.
