I remember sitting in the theater opening night staring at the lightsaber, confused. I knew it had just been broken, but I hadn’t seen it since the flash of light. Maybe I missed something and the movie will explain it later. (whenever theres something in a movie I don’t understand I trust that if I just keep watching it’ll make sense down the line). Up until the lightsaber I honestly just thought that Luke cleaned himself up and came through the back door. I was so caught up in the moment of it all that when Kylo slashed Luke and he was unharmed I was freaking out, and then the reveal moment knocked my socks off!
