That? That right there? That idea stops Luke in his tracks. There's no hiding his Force signature now. He opens his mouth to speak and, closes it before saying anything. He is used to pain being something to pass onto the Force, or something that is considered his due as a Jedi, and pointedly refuses to use it as a base of power, but valid? That's not a concept that has ever occurred to him.

Once it does, he thinks over what else he knows of his friends, his family, and while he would never tell them to release their suffering, perhaps he should have acknowledged and validated it.

"Sidious wanted to take me on as his own. I was only in his presence the once and it was too much for me. I can't imagine how - no, I don't even want to think about what he could do." The idea makes him shiver and some of his more lightning damaged nerves shudder and twitch as if in sympathy. "I wondered about Anakin. Why he ...just, why, but all Obi-Wan said was that Vader killed my father and left me on a moisture farm."
