I'm in agreement to still having questions. Mostly ones like your last one, and what is the Stick/staff that Ahsoka is wielding. But also, we don't yet know where Ahsoka went after she escaped the World between Worlds. Ezra did tell her to "come find me" I kind of wonder if maybe as they were running through the rooms, they caught a glimpse of how the battle of Lothal would go down, and maybe possibly where Ahsoka and Sabine find Ezra and Thrawn (because Filoni has confirmed they are both still alive). Also, wouldn't it be Jacen Jarrus or Jacen Dume? Lots of stuff to ponder, but I kind of really hope the next series that Filoni makes is about Sabine and Ahsoka searching for Ezra. I really don't want that to be in a book.
110% agree. A book would be good but I NEED to SEE this adventure.
