So I re-read my theory of Jax out loud and my little sis -who was in a video chat with me- told me that that idea was, not only out of character, but also it didn't make sense. She told me to re-watch the serie -which gladly I did.-
She's right! The series is COMEDY violence to existential crisis not angst. It's only 9 episodes, and it's better not to force it and make it much longer.
If anything, Jax would say it but not actually mean it. I think that phrase will go fine in something like this:
(Probably in a hunting/chasing/or a scene where they need to make a trap for some reason.)
Jax: "We're going to offer a sacrifice... a Gangle sacrifice."
Jax: "Because no one else looks like dead bait. Now throw yourself to the floor."
Jax: "No, I want you DEAD!!! not preparing yourself for nap time."
Jax: "Gangle, what are you doing?"
Gangle: "You told me to-"
Jax: "I want you DEAD!!! Do it correctly or we will be replacing you with Bubbles."
Ragatha: "Are you sure about this?"
Jax: "Of course. Who else than ribbons? It was a lost cause anyway."
Ragatha: "Will this work?"
Jax: "It better, otherwise I'm blaming Gangle for her bad performance."
Either way, it works with Gangle or Pomni. That seems to be correct, Jax is more into rude comedy and not angst; something close to the Looney Tunes, hurting people or watching them get hurt but in a funny way, never crossing the line. There's a reason whe never cursed; you can be a jerk without needing to use bad words.
I love both of my theories 🥰 doesn't matter which one happens, it's fun to try to guess what could happened....
Pd: I still think Jax has a bigger roll in the show.
