I am really curious as to what will happen with Law. Here are some possible scenarios:
1. Law gets caught. Seems very possible but for some reason i don't like this. It will be a classic let's save our friend scenario after, and it's not like Law is really trustworthy and good enough to sympathize with him. I just prefer the wackiness that we have been seeing without stupid restrictions such as save x person in the next x hours. Also Law has been portrayed as a smart and cunning man, and i doubt that his plan will crumple so easily... Even if he was planning for Fujitora and DD to clash in this island when he didn't knew that DD didn't leave the marines, he still should have accounted for the possibility that Fujiotra would come after him too or something. And if Law thought he could escape from Fujitora maybe he can escape from Fujitora + DD too who knows...
2. The gnomes save and hide Law. Seems very possible and something i would like to happen. We already seen how fast gnomes are and how they have good hiding places, so if DD hasn't seen or felt Law's presence yet, i think that Law can still hide quick enough to not be found.
3. Law has an ace up its sleeve. He surely has an ace up its sleeve, the question is will it work against both Fujitora and DD?
4. Law speaking it up with Fujitora and betraying the SH's temporarily so he gets the marines with its side for a while (if this is possible), in order to get out of this situation. Don't forget that Law has not been dropped from the Shchi yet and iirc Akainu said that Law should first be questioned before making a decision.
