Upon entering the Taris Grand Arena, Ben Solo, who takes on the alias of Timm Caleen, kills a couple of gladiators before the very eyes of all those watching, before eventually facing the Champion. However, Ben sees a terrifying revelation when the Champion shows his face, revealing a battle-hardened and bloodthirsty Jacen Syndulla, who Ben and the Knights of Ren dumped on Taris several years earlier.
