"you'd have to be blind to not see that. how she instantly can't say anything against him and agree w/ everything he does and says." I've heard this for ages and I still don't get where people get this at all

this is a thing that never happens

the closest to this happening is when Sakura asks what's going on outside Susano'o and he says "Why does it matter, you can't do anything anyway" and she looks sad

Which is approximately a billion years after people started saying that

I can't think of any time she does this

he reprimands her rightly a few times as teammates

and that's it

she can't bring herself to kill him because she loves him too much, and she can't make him turn away from his dark path because no one can

that's it

that's not her being helpless, though
