Kid. Please pay close attention to what i am saying. My whole scenario is during the act of Itachi being warped by Obito. Wtf does not being able to touch Itachi through susanoo have anything to do with it.
Getting agitated there huh?
YOU said that he will warp Itachi, then Itachi activates Susanoo.
He can't activate Full Susanoo in 1/1000th second, that was Incomplete Susanoo that's why the Incomplete one is what we see when Itachi gets up.
Since he can't activate it that fast YOU said that he can activate Full Susanoo in 3 seconds and stab Tobi with Totsuka.
The moment the Susanoo starts forming the warp will be canceled because Tobi can't hold him through Susanoo.
He has to be HOLDING or TOUCHING someone to warp them.
Get it now? Cause it's pretty annoying explaining this to you.
