...helping Supergirl fight Reign.

...working with Supergirl to save Sam.

I’ve re-watched this scene too many times to ignore this.

Kryptonite is made out in the show like it’s the only reason there’s a rift between Lena and Kara, but it’s not. As much as we spent an entire episode insisting that Kara wants to redeem/liberate the human side of the Worldkillers, it’s clear from this dialogue that at this point she’s solely focused on defeating Reign. The show in general moves from Kara-and-Sam-centric (hello 3x05) to Supergirl vs. Reign, but Lena just wants to help her friend get better. Over time, we see Kara Danvers appear less and less in the show until she’s essentially Supergirl in a braid and glasses. Lena, on the other hand, is so focused on saving Sam that she, too, is losing touch with her human side, absorbing herself in science. Without each other to remind them of what it means to be human in their own way, they are lost.
