I like to think that Vader and The Emperor just hung out in their downtime.

I imagine them just calling the other one up and saying “Are you busy? No? Ok. I’m gonna come by for a bit.” Then they would just sit in silence, staring out to space while casually exchanging telepathic thoughts on what they see in the stars. via /r/StarWars https://ift.tt/2UpY4BU
