The air of ambiguity surrounding the Joker card from Alice in Borderland season 2 finally makes sense following the new announcements about the show's return. All seemed to have ended well in Alice in the Borderland's closing arc when Arisu and Usagi defeated the Queen of Hearts and found their way back to the real world. Although the couple could not recognize one another after returning home, the show ended on a positive note by hitting reset on their relationship. However, one dark twist in the closing moments left viewers wondering whether Arisu had escaped Borderland.
