Upon Hugo's request, Albert turns his head towards him and looks up, his face seemingly undecided on what expression to display. You know that Albert's secretly quite thrilled by the idea of seeing two grown men beat each other to a pulp, but none too enthusiastic about sleeping in the dormitory when mrs. Fines finds out he's been attending such an event. His mouth starts forming words, and after a couple of seconds - with a sigh - settles on "You can tell that to Mellie...", with a nod of his head to indicate she's in the back.
Meanwhile, as he discovers Josie's intervention and leans out to look past Hugo to turn his attention towards the door, says "Now what's that girl getting herself into now?" The way she reads people is unnerving, Albert'd just wish she would be a bit less conspicuous in the way she confronts them.
Hearing Hugo shout and realising a little impetus will be required, Albert jabs him in the side with an elbow and says, semi exasperated, "Well, go on - if you're just going to stand around here you might as well take tonight off, too."
The customer - who did indeed give slipping past Josie and towards the door a couple of tries - seems to make up his mind in a split second and saunters towards the door to the lavatory instead, as if nothing happened.
