Yeah, that's pretty much the way I can see him doing. I mean anything that is forced on something, especially on her master, will not make Sakura happy in the slightest. I do wonder if Sasuke is aware that Tsunade is close with Sakura, let alone Naruto, so doing a small thing to Tsunade like making her submit her title to Sasuke is something that Sakura should slap Sasuke for. But we don't know exactly what Orochimaru will do in this moment. Could he just help her like a good person, make a price for it, or kill her altogether? We don't know but it's suggesting darkness awaits. We have to wait. The sad part is that whatever he do, we have to wait longer since it took him a while to get there.
I'm wondering if Oro will use Tsunade as a bargaining peice or some sort of hostage to force Naruto an Sakura into submission. Be a perfect way to keep both in check if Sasuke wants to force his way to the hokage position until she Is freed from Orochimaru.
