ANOTHER reason to not directly reference the Star Wars books is, having not read them all, panel one could be wrong for all I know.

I mean, I'd be surprised if one had been established in the Expanded Universe era. I suppose one could argue for a multiverse existing now simply due to divergent official canons.

References

My hope is Justin is amusing enough for this comic to be amusing even if one is not knowledgeable of the series being referenced. 

Funnily enough, I don't think either series being referenced is consistent about time travel. It's the norm in Star Trek for time travel to change the future, but then the 2009 movie casually strolled in and was like "oh hey I created a new reality using time travel so everything is still canon deal with it".

Then there's the Back To The Future movies, which are their own rabbit hole of logic regarding how time travel does and doesn't work.

It's not a rabbit hole I've spent much time in, so I'm not actually sure how much I'd agree with Justin (if at all). It's contrary to what the first movie obviously wanted to imply, however, so that's obviously the side of the debate Justin's going with, darn it.
