[The tunnel is fairly short, and sure enough it leads out to some bushes just outside the commons. The area isn't too well traversed right now, but there is some traffic]

All right, next step. See those boxes over there? They'll get us on to the roof. We cross over to the large oak which we can climb down and into the wooded area. There's a trail that leads to the dorms, if anyone's jogging it they're skipping this thing too so it won't be suspicious.
