Sanvers breakup confirmed

As much as I like the character, this is probably the way to go. At least with an amicable breakup they have the option of getting back together in a later season, once whatever it is that broke them up has been resolved.

It also frees Alex's character to do things like flirt with Sarah in the crossover. (Which she will finally participate in, thank Zeus)

As far as love interests for Alex I hadn't much thought about it. Perhaps have her date causualy rather than have her jump into another serious relationship?
I suppose with Rein they can do something similar to what they did with Alex and Max in the first season except it would be less one-sided this time, since Alex would actually be physicaly attracted to her.

Are there any theories as to the reason for the breakup?

My hope is that Maggie is offered a position as head of Gotham's Science Division, which would require her to move to Gotham. This is a huge opportunity for Maggie and she understandably wants to take the position. Alex of course doesn't want to move to Gotham as it's far away from everything important to her, but she doesn't want to hold Maggie back. Realizing they want pursue different things they breakup.

This would also be a good way to show Kara that love, by itself, isn't always enough of a reason to stay together. Sometimes other practical concerns need to be taken into account.

I really liked Sanvers at the start. It was very touching and inspirational. But then Alex got kinda weird about it and the two were taking up too much time with arcs that have not much to do with the rest of the gang.

So I guess this is a good thing, for the integrity of the show.

I tend to agree. One of my biggest complaints in season 2 is how everyone was off doing their own thing in almost completely separate storylines, instead of great ensemble pieces. Sanvers was part of that. Yes, it was very touching and important, at the start. But it did take up a lot of screen time.

I feel like the Sanvers shipping community is going to lose their minds, and we're going to have a world of backlash. But Floriana was never meant to be a full time cast member, and was never meant to ride out the rest of the series. Even the producers admitted that. And if Floriana has found a full time acting gig, then we can't really blame her for leaving. As an actor, you go where the work is.

None of this erases Alex's growth, and how she will progress throughout the future of the show. But I definitely look forward to the dynamic coming back to the core cast.

Though this may be true....I would not trust Ken the Paparazzi on anything.

Get ready for the hate storm from the Sanvers shippers...

I agree that with Floriana leaving that Sanvers breaking up was for the best. It would be hard to show a relationship without having Maggie there at least part of the time. I mean if Alex was fighting then it seems like Maggie would be with her so it would not seem realistic if we didn't see her some of the time.

I would like the show to focus less on romance so if Alex stays single that's fine with me. Just have her hanging out with Kara, Lena, Jonn, Winn, James and Sam (Reign). That being said I think some flirting between Alex and Sara in the crossover would be great. Also, I think it would be hilarious to have Kara help Alex get ready for a date like Alex did for Kara in Episode 1.
