What might the title refer to?
The important thing is that the marines got there after Blackbeard destroyed this place and there is also no information regarding those killed or captured. Which is why Luffy doesn't have to worry too much about Sabo, because if he did get captured, it would have made its way into the news.
Kaido has also been informed about Jack's situation and him not being able to retrieve Joker. He is also full aware Luffy and Law are the ones to blame but isn't worried about their power in the slightest. Furthermore, it looks like he clashed with Kidd, as the later is seen beaten up behind the cell. Wasn't Kidd and his alliance supposed to go after Shanks? I smell something fishy about the Kidd-Hawkins-Apoo alliance. I mean, Apoo was shown in last chapter that he is associated with Kaido somehow, so...
Blackbeard attacking Baltigo is not surprising, but what leaves to be questioned is, where the Revolutionary Army is now, because from the news it was only shown that their HQ was destroyed, nothing else from the Army itself.
But with this, the Rev. Army is making its presence more known than before (well, it actually started to do so since Dressrosa with Sabo's presence there).
