Season 8 - Episode 16: "Wrath"
Scene: Gabriel speaks to God; Rick reads his own letter to Carl.

"Dear Carl,
I remember. I forgot who I was. You made me remember. I remember that feeling, walking with you that day. Like I finally knew who I was for the first time in my life. Thing is, we were walking side-by-side, but you were bringing me somewhere. Bringing me here. Bringing all of us to the new world, Carl. You showed me the new world. You made it real. I see it. I remember.
- Dad."
