When you mentioned the device in your post about Lena knowing Kara is Supergirl got me thinking (and maybe this has been discussed already, idk) what if Lena's biological mother wasn't human? Listen, what if Kara didn't actually damage the device and a) Lena thinks the green response is what she was supposed to get and doesn't know she (herself) isn't human, or b) she knows and the device confirmed her Kara is not human either. Part of me thinks the writers are not that smart, but what if?
I SAID THE SAME THING ON TWITTER!!!!!!! Listen! If lena’s mother was an alien indeed and her father knew then isolating lena from lillian would be logical since lillian is not alien friendly at all. I dont think supergirl’s lazer eyes effected the device. I think the device was working just fine. I even saw someone say that the president could very well be lena’s mother because Lillian is full of shit seriously why would we believe that lena’s mother is dead? I also think this could be why lena’s father took her away from her mother maybe because he figured out she was an alien and wanted lena away from her?
