Supergirl

I re-watch Supergirl season 2

When Alex met Maggie's ex girlfriend Emily she told her that Maggie was cheating on her that led to their breakup.

In season 3 Alex and Maggie broke up because Alex wanted kids but Maggie doesn't. So what if Emily told Maggie that she wanted kids and it caused her to cheat on her so Emily would be the one to break up with her?

Natalie Abrams was a co-writer for Earth Prime Batwoman comic ‘Flesh and Mud’ and she has now confirmed that Kara and Lena are canon in the Arrowverse. Only took around 7 years for the confirmation even though in our hearts and mind we knew it was canon all along.

Check out this series of videos by "The Blockbuster Buster" on Youtube, called "A look back at the Arrowverse" This 4 part series, roughly breaks down each Arrowverse show from it's creation, premise, crossovers and impact. I can't put links to the videos, due to restrictions on this wiki, but I'll place images here to help you find them on Youtube.

Part 1 - Arrow, Flash. Flash vs Arrow, Heroes Join Forces

Part 2 - Supergirl, Worlds Finest, Legends of Tomorrow, Invasion and Crisis on Earth-X

Part 3 - The Arrowverse's decline in quality, Batwoman, Black Lightning, Elseworlds and Crisis on Infinite Earths

Part 4 - Armageddon, Stargirl, Superman & Lois and the cancellations/ending's of the Arrowverse shows

Hope you find these handy and enjoy them.

Of course the writers had to implement an excuse why they couldn’t make an appearance in The Flash in ‘Wildest Dreams’ but I can’t stop thinking why they’re off world.

Side question:

I wonder why Lena or Kelly don’t partake in their monthly mimosas brunch. They’re part of the Superfriends, especially Lena. Could it be that Flash writers aren’t caught up with Supergirl’s storylines?

These relationships can only have lasted up to one season and the couple can't get back together in a later Season.
