I’d say Ahsoka is a central character of The Clone Wars, but only a supporting character in Rebels. I think Ahsoka showing up in a cameo or as a supporting character in The Mandalorian and elsewhere is a great way to add a lot depth to whatever story they’re telling. We still follow the main character and their story, but whenever they connect with something larger, even if brief, I think it’s great.
I think we have a lot of Ahsoka still ahead, but when her time comes, I expect it to be huge.
