Well, they could just buy the contracts back at a much lower price as time decay and (them assuming they're correct) the share price dropping significantly lowering the intrinsic value of the calls. Also, if we trade down to the $5's or single digits, I'm sure that would mean there is a lot of selling going on. Just giving you my view of what someone selling a bunch of ITM calls would be thinking..
