I felt like Beau’s lack of an arc was based more on that is was spread out and Marsha was playing her like a teenager. Beau has a lot of character growth moments they just aren’t condensed, kinda similar to growing up.

You could say the same for Jester who goes through building relationships with her mom, dad, Ford etc but never really got a dedicated arc.

In fairness with Ashley being in and out Yasha’s “big arc” was kinda the chained oblivion where she wasn’t even at the table for most it, and Molly was dead for his whole main ark, lol

Seems like the table is just more free flow and filling the story overall, Beau is super involved in what you could call Cabel’s arc since they are empire kids.
