Canon
Kara and Mon-El start off rocky as they are from rival planets. They manage to retain a friendship but when Mon-El is dying he kisses Kara in what he thinks are his 'dying moments' (Medusa 2x08). He convinces Kara that he doesn't remember kissing her but admits he remembers in 2x10 (We can be heroes) after he saved her instead of the civilians. Kara rejects him and he goes on to get a lunch date with Eve Tessmacher. In 2x12 (Luthors) she admits she has feelings and a creature from the 5th dimension shows up but he is defeated. Kara and Mon-El finally get together at the end of 2x13 (Mr. & Mrs. Mxyzptlk). They go through they're ups and downs but Kara breaks up with him in 2x16 (Star crossed) which is the first part of the musical crossover with The Flash. Ultimately they get back together in the end of the musical crossover. Unfortunately in 2x17 (Distant Sun) Mon-El's parents put a bounty on Kara’s head, which forces him to sacrifice himself and go back to Daxam; Kara is heartbroken and saves him and they are happy until, Rhea decides to convince Lena to help her by deceiving her in a side-plot in 2x19 (Alex). With Lena’s help Rhea builds a portal for the thousands of Daxamites who survived Daxams demise in 2x20 (City Of Lost Children). In 2x21 (Resist) Rhea essentially kidnaps, both Mon-El and Lena, and forces them into marriage, in an attempt to bind Humans and Daxamites. This plan was foiled by Kara, Alex, President Olivia Marsdin, Cat, Lillian Luthor and the original Hank Henshaw. Lillian and Hank, take Lena to safety but leave Kara and Mon-El, on the ship the president has ordered to be definite grated by th positron-cannon in th DEO. Kara gets Mon-El to safety, but stays on the doomed space craft. In the Finale (2x22/ Nevertheless She Persisted) Superman destroys the positron-cannon, and thinks Kara is his worst enemy, in the fight Kara defeats Superman, being declared as the champion of earth. With the fight leaving her breathless, she, Alex, and Kal-El go to the fortress. In the fortress Kara dreams about her and Mon-El. After waking up they go back to the DEO, where she and Mon-El Reunite. After evoking a trial by combat wit Rhea, Supergirl trains with Superman to help her beat Rhea, and save Earth. Meanwhile Lena and Winn are working on a device that would spread Lead, which Daxamite are severely allergic to into the atmosphere, making the planet uninhabitable by the daxamite race. After Rhea does not homer the trial by combat, lead is released into the atmosphere, forcing Kara and Mon-El to separate. In the goodbye, Kara finally confesses her love for Mon-El, while giving him her mother’s necklace, telling him it would keep him safe. He also tells Kara that where ever he goes he’ll be a better person because of her. After tears were shed and space pods left the earth atmosphere, a portal opened up with Mon-Els pod going into it, leaving KaraMels love story on a cliffhanger.
