Unlikely. Leo is sort the fool of the group, the funny but underappreciated teammate. In my experience the fool rarely dies in these kinds of stories. (Merry and Pippin from LotR, Xander from BtSL, etc) This is probably because their humor and their desire to belong makes them very relatable to fans. To kill them would incite an angry mob.
