This chapter was sooooo good!
Can't believe some people actually think Doflamingo is dead, guess Tontatta are real.
And about Law being the one to save Doflamingo… I don't know. The thing is, even though Kyros is super fast, his attack this time was not fast at all. After he started runing towards Doflamingo, Viola had enough time to explain Sugar powers and even Kyros' past to Luffy. Even King Riku saw Kyros coming and talked to him before he landed his attack. If all that happen before he could strike Doflamingo, you can be completely sure that Doflamingo could have avoided that hit. If he didn't act, if Buffalo and Baby 5, standing right there, didn't act is because they knew Kyros couldn't do shit.
So, unless they were all expecting Law to save Doflamingo I would say it was something Doffy did himself.
Also, why are people discussing Doflamingo's CoO? He saw Kyros coming with his own eyes one page before the attack, he wasn't hit by surprise.
