I don't even need to see her in a lewd scene (most definitively
not telling you not to do it, Kay?), just
some asshole-x dropping her naked from an ambulance, in the middle of a cow pasture, with only a pack of dry ice to cover herself with.

Chad firmly believed MC was blackmailing him, this is indisputable. He also didn't realize some of Crabieth's photos were too old and in odd angles to be taken by MC, which Anthony figured out in 1/2 second.
Blackmail is a power play and it's easier to get hold of a dog if you're at its side, holding the leash; it's not only about getting the victim to do something, but also keep his/her mouth shut afterwards. Unless the blackmailer needed Chad to do a very specific one & done task, which the line
"What do you want from me?" suggests otherwise, it would make more sense to come out of the shadows.
