YMMV / Miraculous Ladybug S05E13 "Migration"

• I Knew It!: Ever since "Wishmaker" had Luka learn Ladybug and Cat Noir's real identities, a few fans have felt that one of two things would happen: Either Luka would eventually reveal this knowledge to Ladybug in a moment of desperation, or he would be forced to leave Paris in order to run away from Monarch. This episode has both things happen: Luka reveals to Ladybug that he knows she's Marinette and that he knows who Cat Noir is (though he doesn't tell her who he is), and at the end, Luka decides to go on tour with Jagged Stone in order to get away from Monarch, who ends up learning he knows their secret identities.
• Salvaged Story: Ever since "Wishmaker" had Luka learn about Ladybug and Cat Noir's identities, a few fans have felt like this information hasn't done anything to advance or affect the plot, as Luka hasn't had a major focus and whenever he appeared, this particular plot point never came up. This episode finally addresses the elephant in the living room by not only having Luka reveal he knows the identities to Ladybug, but deciding to leave Paris in order to run away from Monarch, who also ends up learning about his knowledge.
