Ren is powerful but I wouldn't compare him to Palpatine in many ways despite the fact they both used the Dark Side of the Force.

[Granted Hux knew very little of the Force or the Dark Side but had a difficult time relating Ren to someone like the Emperor.]

Palpatine had foresight, he was a keep observer and used his resources wisely from what I've seen in the records. He didn't openly display his powers, he didn't need to. It wasn't widely known that he was a Sith Lord until after his death.

[He was silent for a moment, considering his words. She most likely had seen Ren's powers firsthand and was in a better position to have better insight than he did.]

I would consider him more similar to Vader in many ways.

[Given that Ren is Vader's grandson and all.]

I'm aware of the power he wields though. I know what he can do, I've seen it firsthand. And perhaps I should be scared but I know that he doesn't dare kill me.

[At least for the time being.]
