i’ve seen some conversations about how much alex has given up for kara, especially in season 1,and talk about how lopsided their relationship is but they conveniently leave out that not once but twice kara gives up her world as she knows it for alex–she exposes herself for alex, as she talks about in the cult ep in season 3, and the people in the plane just got lucky because she only did it because alex was there. she turns her life upside down without hesitating for her sister. because sure, Kara loves being Supergirl but her life got so much harder and dangerous after she did–and we’ve seen how much Kara hates change. This has been her life for the past 12 years, and she doesn’t hesitate to turn all of that on it’s head solely for the sake of her sister
and she gives up her greatest fantasy as well: Krypton and her family alive and whole, her aunt alive, neither of them have ever been in the phantom zone (because i think a lot about what kara said to astra–how astra looked at miles of never ending black space and how something inside her died and is she really talking about astra? or herself?). This is what she wants more than anything else–and it just takes a few words from Alex and she willingly chooses to lose them all once again
if alex’s tagline is “i come back with my sister or i don’t come back at all” then kara’s would be “there is no world worth living without you in it.” And I don’t think the severity and depth of that kind of devotion should be underestimated
