At first, there is no indication that anyone really noticed it. After all, engrossed as Evan is in his file and Viana in the television, it's entirely possible, even for a noise that loud. A few seconds pass. Eventually, Evan lets his knees slide down, and he glances at Viana, amused, before both of the turn to look at Bentley, raising a simultaneous brow (both the left, both at the same incline).
