Vibe-Checking: Alongside what he'd normally pick up from Leeds, he might catch a weird echo or feedback sensation, where he can sense his own wants and needs coming back to him from Leeds. (Alternatively, if he's around Leeds and at least one other person Leeds can sense, he might notice feelings coming from Leeds that don't quite match up.) Since he's not going to be probing deeply under normal circumstances, he'll probably notice this only if/when things get emotionally intense.

Mental Blocking: If/when he learns about Leeds' ability, he can probably use this to block himself off from the big guy temporarily. The compulsions are definitely more of a passive thing, so they won't be actively pushing through any defenses. Not sure how long he could keep it up, but I figured it was worth noting!

Hacking: Willing to play with this if it comes up! Just obviously need to talk out the details OOC when it happens.
