Kara hasn't heard from Alex in months, not since she had entered college. What Kara finds when she decides to visit shocks her to the core as she begins to truly realize that her sister is lost.

Alex was supposed to be the strong one. Kara had never seen her older sister cry or need comfort. But when Alex needs her most, Kara is there.

My version of the fight between Kara and Alex at the end of 1x19 and beginning of 1x20.

Once Alex decides she's going to save Kara, nothing is going to get in her way. Not romantic, I just have a lot of sister feels.

Alex is injured during a rescue.

Kara is falling apart after the events of 1x16, luckily, Alex is there to help her out.

Supergirl was taken by Cadmus, Alex's team goes in to rescue her.

In the fight during "Myriad" and "Better Angels", Eliza isn't able to break Non & Indigo's mind control hold on Alex...and things go too far.

After almost losing everything, Alex thinks she understands Kara just a little bit better now. Set during and after 2x15.

"You both go first! I'll cover you!" The goal was getting Jeremiah out of Cadmus; but missions aren't always as planned and this time, while they took someone out, one of them was left behind.

Alex knew her sister was headed for a breakdown. She expected it. She did not, however, expect it to be this colossal.

Kara is being stalked by someone from the past who knows a lot about her and her family.

"There's an instant- a split second before the world turns black- where she manages to catch a glimpse of who Maggie had been crouched over before, who she'd refused to let Alex closer to. A girl lying motionless, a red cape crumpled underneath her and blood smeared over the stylized "S" on her chest. Supergirl. Kara." - Rated for language, more warnings within.

"It's okay, It's okay. Just… Put pressure on it, can you do that for me?" / Season finale theory. / Danvers Sisters

What if Kara had indeed gave herself up to Cadmus and the DEO couldn't rescue her on time? (This is a tragic story guys; the other side of the coin. Don't read it if you don't like sad endings.)

As Kara struggles to work out where she belongs after recent events she becomes more and more isolated from those around her. Set just before 2x12.

Separate crises on the same night leave Kara, Alex and the DEO reeling. As old acquaintances remerge little do they know the real danger is just beginning and will threaten to destroy the Danvers family forever.

When Kara stumbles into a trap she and Alex share a few final moments before the Kryptonite weakens her completely.

My take on what could happen at the end of Myriad

Stressed by Kara's disappearance, when Kara finally returns to her Earth Alex has to decide how to greet her.

When Alex disappears Kara, Maggie and J'onn have to work together to figure out who has taken her. But as Kara's worry builds she is tempted to sacrifice her ethics to get results and find Alex before it is too late.

When Alex and Kara face the Cadmus threat Alex must make a choice that will change her life forever. This is set before 2x08 "Medusa"

Kara finds herself at breaking point following the events Falling and needs support from both Cat and Alex.

Still recovering from being taken and nearly drowned, Alex's word is turned upside down again when the situation is reversed and her family is placed in danger by a group wanting revenge.

With Alex and J'onn away to face the music for their recent inability to follow orders, Kara has to help her cousin before it is too late. During the showdown though her cousin can't help but let his repressed thoughts out, hurting the already fragile Kara. Set a few weeks after the S2 finale.
