Really? She spends her time killing her way to finding Thrawn. Refuses to train Grogu. Very reluctantly trains Sabine.
She killed some people who were hurting innocents. That's the same stuff she did her whole life. Refusing to adopt a kid doesn't mean you're emotionally damaged. We never
saw her train Sabine, so we don't know why she started in the first place, or why she stopped (other than maybe that, y'know, Sabine has no Force powers).
Everything about her screams damage. No emotions. Keeps everyone at a distance. Refuses to have anything to do with the New Republic and rebuilding.
The entirety of the prequel trilogy Jedi were emotionally muted too. Again, not wanting to bring along Sabine makes sense if the viewer has only seen this show, and thus thinks Sabine is kinda wimpy and disengaged (unlike the skilled, clever, motivated person she was in Rebels). And we're also shown that the New Republic kinda stinks, so refusing to have anything to do with them doesn't make her damaged, no more than me choosing not to get involved in my own country's politics.
Repeated lines: evil Jedi talking about her legacy. Her own line about abandoning Anakin.
When she was fighting Baylan, he said her legacy was destruction or whatever, but that seemed to have no effect on her emotionally. She was kicking his butt beforehand. She kicked his butt afterward. She only lost the fight because she burned her hand on the orb. She didn't comment on his thesis. Her facial expressions before and after were equally intense. She had no flicker of doubt, no gasp, no raged denial. It seemed like he was just trying to get under her skin and it wasn't working.
I’d say there’s considerable support for this interpretation.
I would totally be
excited for a version of Ahsoka where she's showing stress and anxiety. Have her see Sabine get angry at doing badly in her training, and have Ahsoka respond by saying that she needs to suppress her emotions if she wants to be a jedi; and then have Sabine push back and say that when they first met, Ahsoka wasn't
this suppressed. She knows it had something to do with when she lost her battle against Vader, but Ahsoka never talked about what happened. And Ahsoka shuts that conversation down, and walks away, and has to calm herself.
And hey, after they fly through the Purgill and land after nearly dying, maybe Sabine and Ahsoka could have a moment of joy at their survival, only for Ahsoka to catch herself, look off, and tell Sabine again not to be emotional. Which could piss Sabine off.
Then hey, you're actually
showing Ahsoka struggling. You're giving Rosario Dawson something to work with. You're hinting that she has unresolved issues.
And then you can have Anakin show up and force her to talk about it. She tries to stay emotionally muted, but he keeps assailing her with stressful memories until finally she pushes back. Let her unburden herself of years of resentment toward her old master. Let her
yell. Have some
drama in this show!
