I recently watched the animated movie first flight and I am about halfway through emerald knights. My question is are these movies completely separate and not part of the same timeline? In First Flight, Sinestro meets Hal and then pursues the Yellow Lantern. There seems to be no gap as where the Emerald Knights could fit in. With Emerald Knights Sinestro is back to being a Green Lantern and him and Hal have know each other for a while given Hals conversation with Arisia Rrab and Arisia is in both FF and EK.
