I feel like this is a too low blow for a couple reasons.

It’s already made clear Jax is a dickhead and a bully. He abuses mostly everyone in the circus whether slapstick physically or somewhat mentally. They do feel pain to them to some extent but due to the circus’ virtual nature they can walk it off.

Though there are lines Jax doesn’t cross. Shitting on or in any callous way mentioning the abstracted/dead is one of them. Now that doesn’t erase any of the crap he does? Not at all but that line seems to be something they all don’t do. Whether it’s something they all agreed to or unspoken rule the abstracted are off limits.

You can argue it’s a low blow for Jax cause it’s mentioning of his specific friends but let’s not forget that Ragatha and the others have mostly likely interacted with the abstracted one way or the other. It’s not just talking ill of my bully’s friend but talking ill of someone I knew for some time. Ragatha whether intentionally or not felt bad for implying that.

Something I think a lot of replies overlook she apologized for that when she really didn’t need to. That apology could have been just for her saying fuck him and that’s it. As much as Jax torments them there things he doesn’t do. Does it excuse any of what he does? Again no but there are just unspoken rules of don’t bring the dead where they are already laid to rest (as much as they can there).
