In one panel Shaka realised that the Sunny is in danger. I think he will convey that thought to the Straw hats next to him. Maybe some of them will run there first, while the others will try to find Vegapunk and Bonney.
Or Bonney and Vegapunk will come upon the Sunny first.
Another thought of mine is, that Lucci and Stussy will leave Zoro to Kaku and head into the facility further to find Vegapunk.
