[@Tracyarmav] you should use omething you don't have a good understanding of. If receptors are blocked you need to know why, how they can be unblocked. Let's say for example his feeling receptors are blocked except when he thinks of his sisters. That means he wouldnt care how Vad treated the others because it doesn't involve his sisters.

Not directly, but indirectly it affects how long he's going to be stuck here, NOT looking for them. Sooo he would care, and the kind of possessiveness Vlad's been exhibiting would demonstrate that he never intends to let them off the leash, which means Isa'd never get to see his sisters... Does that make sense?
