"Protecting people is what I do, you should know this by now"-Kara Danvers to Lena Luthor "Protecting you is what I do, you will know this from now on"-Lena Luthor to Kara Danvers The writers were never able to make Supercorp Canon, though they clearly wanted to. So instead they used double meanings in everything. One of those hints they sent was Andrea Rojas. They made sure we saw Lena had feelings like she did for Kara before. You can't tell me the Andrea thing was am accident by the writers. They used parallels in that entire relationship right as Supercorp was at its largest in popularity. This was to tell us Lena had deep feelings for the same sex before. So as a Behavioral Health Professional I have a breakdown that I think Supercorp fans will appreciate. Lena broke the way she did because the things she was hiding were brought to the surface and not just her denial of who Supergirl was. I'm not saying the show was implying Lena realized she was gay, but they were implying Lena cared for Kara in a way that went beyond friendship. Lena's pain was that she thought Kara didn't care as much as she did. Then Kara did her own speech and Lena realized that Kara was in as much denial as she had been. Season 6 is kind of proof of my theory. Season 6 was primarily Lena helping Kara except herself for who she is. Now this can be taken multiple ways and that was intentionally done by writers who weren't aloud to make them blatantly Canon, so instead they used double meaning on almost everything in season 6. Lena knew before Kara how she felt, that was clear by how different Lena became after she realized how she felt. The rest of the time was her patiently helping Kara come to terms with her own feelings and you can see Kara slowly except these things. Denial can be very very powerful. But if you look, Lena had slowly taken Alex's place in Kara's life and even Alex herself noticed this. You can't tell me Alex would feel okay in letting just a friend take her role in Kara's life. No she felt safe in leaving Kara with Lena cause she saw the connection, the writers made sure we knew Alex knew. All of this was intentionally made apparent to us that Lena had become the most important person in Kara's life and that last scene was Lena telling Kara she excepted herself and all that she is and that if Kara did the same, she would be there for her. Kara taking off the glasses while staring at Lena was a symbol from the writers of Kara excepting herself and an expression of what mattered to her, Lena Luthor.
