Let's be real, a drunk Lena has absolutely asked Kara for a threesome with Supergirl. Most awkward moment of Kara's life (especially given they weren't even dating at that point, just having a gal pals night). And then Lena woke up hungover with Kara sitting by her bedside and looking at her strangely. And Lena opened her eyes, saw Kara's expression, and let her aching head bury itself in the pillow. "Oh god what did I say?"
LENA ASKING KARA FOR A THREESOME WITH SUPERGIRL IS THE BEST THING EVER
