Final Fantasy Type-0
In a mission during the game's second play-through, Joker and Tiz both meet Machina as a White Tiger l'Cie and introduces themselves as they ask him to clear a path for them through the battlegrounds so they can reach Cid Aulstyne. Afterwards, they thank Machina for his assistance and Tiz remarks that the pair of them are like him. She continues to say they will meet again, and Joker says that if Tiz says so, it must be right, before bidding farewell to his "other self" as they leave.

At some point in the game after Machina and Rem turn into crystal, Joker and Tiz request Arecia to release them from their crystal stasis and convince her to erase the Crystals from history to prevent the tragic events brought on by the war from occurring.

In a hidden cutscene that takes place at an unspecified time, Joker and Tiz are seen together in the woods. Tiz begins talking about how the current cycle of the world has been changed, and Joker says that it is unusual. She wonders what she should do now, and he mentions that he has something to report to her. Tiz is puzzled, but Joker says "that person" is not as 'sensitive' as Tiz, so he is going to tell her. She agrees, and asks him to reveal what he has to say. However, he replies that telling her now would be difficult and she knows that. Tiz laughs in agreement, then says, "Let's go, Lean. Lean Joker". Joker nods and they leave.
