I guess I was half right depending on if surrendered is the same as captured.
Tiny glimmer of spunky Ahsoka at the start of her fight against Baylan.
I'm trying not to blame Sabine too much for being manipulated by Baylan, but Ahsoka DID warn her. And yeah figures the mystery guy would be a throwaway.
So is that past Anakin or a force ghost? I'd guess force ghost but he can appear more real in the world between worlds?
And is that it for the Ghost? Ahsoka gets there from where she is now and Hera just goes home?
