As many of you have seen, the finale left us with Mon-El heading back to the future and supposedly it's the end of a two season long arc. But in reality the way Kara and Mon-El ended everything made no sense in terms of everything they had revealed to each other in 3x21 and before then in season 2 and bits in season 3 - They just left without a 'proper' goodbye.

So I am here to ask to spread awareness to the people behind Supergirl that we want Mon-El to return past season 4 to properly complete his arc.
