I think the interrogation/torture scenes pretty much warrant a PG-13 rating. Someone on TheForce.net claims that in one of their viewings parents covered their kids eyes when Kylo was mind probing Rey.
Seriously if you watch he never touches Rey and he also takes his mask off changing him from a monster to a softly spoken young lad. There is nothing remotely hinting at torture in the scene. You can bet there was a version where he kept his mask on though.
He touched and violated her mind with the Force. He even made one of the most rapey statements I ever heard when he said “I can take whatever I want”. Him taking off the mask is an interesting event as it could hint he knew her somehow pre TFA. I hope a version of the interrogation scene does surface when Kylo has the mask on as it would be good for the fanediting community
