Miss peregrines home for peculiar children

I don't think Jacob quite knows what to do at this point in the story. Finally Miss Peregrine deduces that Grandpa Portman is dead, and Jacob explains how he died. She is angry and upset, remembering how she warned him not to leave the island. It is revealed that Emma had been eavesdropping on their conversation, and she is distraught, having been Grandpa Portman's sweetheart when they both lived here.
