We do have the Kaios there. So maybe and but the thing is Zamasu isn't that strong. The only thing I think it did was make Goku Black Immature which is dangers but Goku still has the trick Master Roshi taught him.
And don't forget Goku does have the button for King of All.
Next week we will find out! My guess is we won't see the fuse till the end. We will have a fight and bang fuse time. And I can't believe Whis is an Angel. So if the God dies he goes into sleep until a new one shows up. This story line is getting good.
