Lex is of course going to try and find a way to somehow make a buck out of this disaster. If that means he'll have to offer to take dead tribbles off of someone's hands only to sell the meat or fur as some high quality product, so be it.

And he's totally going to bash any little fuckers who start swarming him, because they're vermin and too cute to be of use. It'll be slow going but... yeah, he's somehow contributing to the extermination!
