[A frown crosses Rey's face, but she keeps her temper in check since Obi-Wan's so obviously ill.]

He won't hurt me, Obi-Wan. He doesn't hurt me. He's had chances, back in our galaxy, and he didn't kill me then. [She hopes he doesn't notice her switching from "hurt" to "kill." Kylo Ren hurt her back in their galaxy, certainly, and it doesn't seem like he regretted it. But killing her she's sure he avoided. Here, though, he's softer, and short of another ghost possession, she believes he'd avoid hurting her altogether.]

That's why he's my responsibility. If anyone can do this, it's me.
