Though they fought hard, the captured group falls and us fans are left mourning the loss. The death of Henry affected Carol and Ezekiel’s storylines as the pair split shortly after the death of their “son.”
In an interview with CinemaBlend, show runner Angela Kang talked about the Season 9 finale.
“The interesting thing is we always went at this season knowing that by the end of the season, I felt like Carol’s fairy tale comes to an end, and she has to go into the next chapter of the story. The sad reality of couples who lose a child is that it often breaks up the marriage,” she explained. “Whether it’s because [the death] itself is the thing that causes the problem, or it just reveals the cracks that were always there, whatever it is; or the grief is so much, and people can’t connect in their grief.
She continued, “That’s something that’s actually a common thing that happens with couples, and we wanted to kind of explore the truth of that happening.”
