The only other episode like that would be 409, the pudding episode.
Hes upset at Negan and upset at the rest of the group for not wanting to fight against him.
So its a really big step for him.
Carl going to the sanctuary is probably my favorite issue ever ofThe Walking Deadcomic.
Had you read that one before you filmed this?
Ive been excited for this episode for years.
The only reason why I was excited for Negan to come in was so I could have that storyline.
The relationship between Negan and Carl is so cool.
Its really, really fascinating, and Im so glad everyone gets to see it.
They kind of just let me go with it.
At that point, he realizes that there is no hope for Alexandria.
They cant live like this.
Theres no way they can.
If they do, then Negan will probably still end up killing them all in the end anyways.
Thats what hes like.
He doesnt need their help anymore.
So Carl tries to go on his own and does what he has to do.
Tell me about what filming this with Jeffrey Dean Morgan was like.
It was so great.
Its so easy to do scenes with Jeffrey because hes such an amazing actor.
You just bounce the emotion right off him.
Its so much fun working with him.
Hes such a cool guy.
But yeah, hes a lot of fun to work with.
All those scenes were so much fun.
Well, Ive known that Carl is very ashamed of how he looks with his eye and everything.
He doesnt see it as a cool thing at all.
Thats a weakness for Carl, and he doesnt want people to see that.
He doesnt really know how to react because no one has seen it before.
He didnt expect anyone to react like that.
Whats the makeup process like for you when we see that eye socket?
It took about an hour each time.
What was it like filming that?
It was weird, me singing You Are My Sunshine while hes pretending like hes bashing someones head in.
It was really, really freaky to see him.
Hes a super respectful guy, but he fits right in with the rest of us.
I mean, I dont think he held back at all.
Its just kind of really a glance with each other that they share.
Yeah, Im not really in any scenes with Norman.
We actually did have a scene back in season 2, but it was cut.
But other than that, they dont really show Carl and Daryl talking much to each other.
