Figure Jacen probably has a good instinct for this sorta stuff too.
Who could I even ask? Her? Can't see that going well. And no one else even knows where they are or what they do.
Sam's not a Jedi or anything. He's already got control of his powers. I can't see it being some training thing. And hell, skulking off with a demon who has a go at anyone else who's near him for some training deal still wouldn't be a good thing.
