Thread , Even though we are a long long ways off for Supergirl Season 6 The Final Season #Supergirl @TheCWSupergirl I have some theories about what could happen in the final season. I know the show is not everyone's favorite but for me enjoy it so here goes , #DCTV #Arrowverse
Theory #1 it has ben speculated that #MonEL and The #LegionofSuperHeroes could return for the final 6th Season of the show and he could reunite with #Supergirl Kara. Could this happen? I would say maybe but would not be surprised if he did. Maybe in the back half of the season
Theory #2 and this one could be cool what if we had a reversal of this cool scene from The #Supergirl pilot episode with Supergirl Kara and Alex the #DanversSisters where this time Kara saves Alex same dialog but different type of scene? I think it would be kind of cool
Theory #3 Will #Supergirl Kara and Lena make up and mend their friendship? Can it be repaired? I think it can but Lena still has a lot of work to do.
Theory #4 will we see other guest #DCTV #Arrowverse characters pop by for a cameo in the final season of #Supergirl ? I think maybe their is always a chance. If any did pop up my choice would be either #TheFlash #BarryAllen Kara's friend or #Stargirl #CourtneyWhitmore
Theory #5 and last one how will #Supergirl @TheCWSupergirl the series end? I think it could be either Supergirl Kara going off with The Legion of Super-Heroes or my preferred choice a #DanversSisters #DanversCouch scene end the show where we began back in Season 1
So those are my theories for what I hope will be a good to great final season of #Supergirl @TheCWSupergirl Season 6 Supergirl fans lets all hope the series ends on a high note. And thanks to @MelissaBenoist @chy_leigh @DavidHarewood etc. for making this great series
