>jack goes back in time, killing aku, undoing the future
>jack still gets sent into the future, moments before he comes back to kill aku
Where did that jack go
is he just going to be spit out in an aku-less future, confused as fuck?
You cant say he's going to be the same as the first time because now aku wont exist in the future, because ashi disappeared
you can't say it created a branching timeline, because again, Ashi disappeared, and that would leave the can of worms of "theres a timeline where jack disapperared while fighting aku with all his friends, leaving no sword and no way to kill aku"
