I don't think Oden was captured here either, because it was mentioned they were still in the castle before Oden somehow sacrificing himself to protect his retainers.
On the other hand, i'm very curious in how Orochi survives this encounter, with it being likely the Grandma at multiple faces will die at some point(not present in the current timeline)
Guess it might turn into a battle of supremacy lasting 4-5 years, but regardless can't wait for the Oden vs Kaido battle
After this, we'd be ready for the Onigashima battle
The drama behind Oden's death should be tragic tho
