Well it seems as though the place in which Kylo Ren puts his helmet on when interrogating Rey has a bit more to it than one would initially think.
That’s too bad it wasn’t explained or suggested in the movie itself. It would’ve been a nice addition.
EDIT:
And here I thought it was just an ashtray.
Were Kylo a smoker, he would’ve been more threatening (jk 😄 )
