I'd so love to see a slapstick fight scene between Jacob and Grindelwald... Maybe like they unexpectedly bump into each other around a street corner. Grindelwald reaches for his wand, Jacob pushes him, the wand falls out of Grindelwald's hands, Jacob tries to take the wand, but the wand emits sparks (because Jacob is a no-maj) and Jacob gets burned, Grindelwald tries to take the wand, but Jacob brawls with him and manages to run away before Grindelwald can pick up his wand looking pissed...

This season already done, so we have to wait for next fall.. I wonder if we will see him in next season..
