-we now know all the visions have been things that actually happened, including Rey being there when the Knights of Ren and Kylo massacre the rest of the students in the rain and then he turns to attack ReyWtf? Rey wasn’t there?! Plus unless Ben Solo had his Kylo mask and black cowl hidden under his pillow then it didn’t happen like we see in Rey’s vision either. You’re taking it way too literally.
Yeah, there is no way the Knights of Ren flashback was related to Ben’s attack on the temple. I could be wrong here, but I believe that scene was actually meant to take place on Jakku, where Kylo and the knights attack a Jakku outpost. The alien that gets slaughtered and his compadres lying dead on the ground closely resemble some characters that were supposed to be like the “Police” of Jakku. Constable Zuvio I believe was the character that they made a big deal about leading up to TFA- he might even be the one that gets stabbed through the chest in the flashback. But I admit it’s been a while since I’ve seen the flashback, so I could definitely be mistaken.
