Everywhere. Always.

So I went to see The Last Jedi-

And all I could think through the whole thing was:
"That Snoke guy must have a wicked headache.   No wonder he's so mean."

Not to mention, Vader had a pretty bad respiratory problem and terrible epithelial injuries from being thrown into a volcano.

Anyhow, I concluded that if Kylo Ren took better care of his crowded teeth and pinched nasal ducts he could probably be turned back toward the light.
