Trying to figure out what Casper can possibly do in this scenario. He's kind of useless unarmed and without any means of opening the door. I'll wait for a few other replies because even if I post again, it will just be a bunch of internal monologues and thoughts that won't really amount to anything.

I'm not sure how many copies he can make or how far from him they can go, but he could start xeroxing out any fallen rubble for everyone to throw at the robot in a distracting manner.
