Mike hops onto the commuter train and head back to campus, figuring that the highest concentration of hot women is probably back at school. It looks like he'll get back in at around 7 o'clock, so he decides to stroll on over to the library, where there will be a bunch of cute female students studying in relative privacy.
He arrives and wanders around the library a bit, acting as if he’s looking for some books. Really, though, he’s scoping out locations and girls he can shrink. He sees a lot of women studying, some he knows and some he doesn’t, but he doesn't want to do this in an area that's going to get a lot of attention.
Eventually he finds what looks like a good location. In one isolated corner of the library he sees four carrels in a row, all taken up by what looks like good-looking girls. Mike hangs back so that none of them notice him, but he decides this is the perfect plan: shrink the girls, put them in his backpack, and head out before anyone has time to notice what happened.
He spots himself about halfway across the room, in a hallway that splits the stacks of books on either side. This way he can hide behind a row of books when he’s not using the gun, so the girls don't notice what's going on until it's too late.
This winds up being pretty effective. He fires at one girl and shrinks her to about two inches tall with a perfect shot. He then spins around to the other side of the row of books and fires at the next girl. He then continues to move down the hallway and shrinks the last two girls, all to the same height.
No muss, no fuss. That was so cool, he thinks, just like an action movie. He walks across the room to pick up his prizes. The girls are all under their chairs, and he quickly picks up an Asian girl and then a cute brunette and drops them both into your backpack. He smiles as he realizes they probably have no idea what's going on, or even where they are. He imagines them in there, confused and asking each other where they are. Funny.
But wait a second: where are the other two? They're not underneath the carrels, they're not on their chairs, and they're not on top of the desks. Mike moves around their backpacks to see if they're under something, but he really can't find them anywhere. This is surprising. Where could two shrunken girls go on such short notice?
