Home is not a place, it is living among those who love and honor you. I can depart this world with peace, because I know my son is home.

M'yrnn

Kara Danvers is my favorite person. She's saved me more times than Supergirl ever could. So, just think about that while you're trying to get rid of her.

Alex
