I would suspect that as Clinton's family aint that wealthy, that prosthesis was probably paid by insurance or by themselves. In any case it would be cheaper model. And truth to be said, CS student doesnt need heavy duty or military grade prosthesis. And for comfort it should be as light as real thing(which is quite light). So i would assume, even if it is not total crap-hand, that it indeed is quite easy to destroy(same as our phones, even more expensive ones are quite flimsy, even if they are largely metal).
And yeah he will totally go to UR for repairs. Could this be start of another friendship, rivalry or even hostility? Will Elliot have problems from his employer? After all he damaged patron without him doing anything(except shouting maybe). Will Clinton defend him before his boss? True, its good it is not friday yet.
