I’m not sure If anyone pointed it out but...
Lena: “Well, when i was first adopted by the Luthors, I adored Lex. When he showed me his true colours, I was crushed. Tried everything to reach him, to bring him back to the side of good but there was no use. I’d lost him.”
Kara: “I spent most of my life wishing I could talk to people that are no longer here.”
They both look so sad when they’re exposed to any glimpse of each other’s sad/tragic past. The look in their eyes, that slight jaw drop, that slow eye blink. Their facial expression is so clear about their feelings for each other, how much they care about the other. It’s mutual. That “wow i would take care of you so hard” is very much real.
