You know what would be really, really cool?! What JJ should do next is have it such that Vader’s red lightsaber gets recovered by Ren! Since we never saw what actually happened to his red lightsaber, we certainly can’t just go on assuming that it got blown up when the second Death Star was destroyed.

I got it! Check this out! Oh, boy, JJ is going to totally rip off this idea! What happened was, when the Death Star blew up, Darth Vader’s lightsaber was shot out by the explosion, it tumbled through the atmosphere, and landed right by the Vader burn site. So when Ren showed up to retrieve Vader’s helmet, voila! He got two for the price of one! He got the helmet and Vader’s lightsaber!

Now if you’re saying, “Oh, Lizard! How could that be? If Ren had Vader’s lightsaber, he’d be using it, wouldn’t he?”

No! You see, that’s part of Ren’s backstory. We’ll maybe find out why Ren doesn’t use Vader’s lightsaber in episode IX.

Wow! The possibilities! We could also have it such that Ren finds Vader’s original bent wing TIE fighter! How cool would that be?! Oh! Oh! Oh! And then Finn will find Luke’s original X-Wing and Poe will find the Tantive IV! We can also have Rey find Leia’s white dress from ANH!

The possibilities! They should totally hire me as writer for the next films.
