Supergirl Season 3 Episode 22 Quotes

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: By the end of this, you will not feel loss, J'onn. You will feel complete. I promise.
J'onn: How do you know?
M'yrnn: Because I know the hole that comes with not doing this, the way I felt when your mother was taken from me, when you were taken from me. Be patient, my son. Let the memories fill you up, as they have filled me up.
