Captive whumpee has their own room, or closet, or cage, and when they enter it whumper won't touch them. They are never restrained in a way that prevents them from fleeing to their place. Whumper will lure them out with food or painkillers, with undoing any restraints still on them, with the promise of a shower, and whumper keeps those promises. Whumpee comes to feel safe in their place, and knows that, at least in this one thing, they can trust whumper.
And then the rescue happens, and the rescuers drag whumpee out of their safe place to get them to actual safety.
