And I am squealing for joy! My favorite TV superheroine and superhero are meeting up later in March for a crossover. I have been waiting for this since these photos of Grant Gustin and Melissa Benoist popped up in Variety. I mean even back then it looked like the two ere having a lot of fun so I can't wait to see these two in character together  

Not sure how they'll be explaining the crossover, whether Supergirl takes place on an alternate Earth (the idea of which is a key part of Flash's  current season) or maybe the events on Supergirl are taking place in the future of the Arrowverse (which would explain why Superman and Supergirl haven't been mentioned on the other shows). Personally I lean towards the former idea as its the easiest way to explain everything. Heck, Barry and company are going to Earth-2 next week on Flash so a gaunt to Earth-SG wouldn't be out of the realm of possibility. 

Anyway I'm really excited to see this. What are you guys thinking? Any villains you'd like to see Kara and Barry take on? How would you cross them over? Do you just want to gush over this LOL. Let me know what you think Flash-SG fans, its been a great day
