Jeff seeing Sera revert back to normal became very surprised but not enough to jump out at the form cause part of him and his gut told him that this ability of his wouldn't last. It didn't mater though as Sera still was starting to break out of his tornado and would be back fighting if Jeff didn't act now. It was truly now or never for Jeff to activate his trump card. 
Boosting down at full speed Jeff charged Sera from above and pulled out the templar bomb from his gauntlet before using every ounce of force he could muster to rapidly spin several times which followed by chucking the bomb into the tornado that was trying to hold Sera down. To make sure that Sera's force wouldn't deflect it back either he then blasted his left wind cannon behind the bomb to make sure that and force that might attempt to stop it would be made to be useless.
