Norman Reedus, who played Daryl Dixon on The Walking Dead, came up with the idea for a season 11 callback to Glenn Rhee, played by Steven Yeun. The callback occurred during a conversation between Daryl and Maggie, where Daryl tells Maggie that Glenn would have wanted him to look after her. Reedus felt it was important for the characters to address Glenn's death, as they hadn't really talked about it since season 7. The moment reinforces the bond between Daryl and Maggie and shows that the memory of Glenn still holds strong.
