So he can tell Kylo he's being a little bitch

It simply says Sith are unable to manifest themselves, nothing about manifesting TO them. Anakin began as a Jedi, and was powerful enough to manifest himself as a ghost without training, and even after living most of his life as a sith. He's underrated.

Not so you forgot about leia

Yeah, do you think the fathers line is thr only one? Where did you think he got his command of the Force?

Well there's the theory that Han could use the force too. But yeah he's a skywalker bloodline.

Anakin -> Leia -> Kylo.

Leia

Anakin has 2 babies. One of those babies grows up and had another baby, this new baby is called Kylo. That would make Kylo the grandchild

Yeah, do you think the fathers line is the only one that matters? Where did you think he got his command of the Force?
For that matter, where do you even get Uncle from. Or are you confusing Anakin with Luke?
