The ending of Deadpool and Wolverine has Wade and Logan destroy the Time Ripper together, and it lets Logan stay in Wade's universe. Spoilers for the final act follow.
Wade and Logan destroy the Time Ripper together and Cassandra Nova dies in the blast. Both survive by sharing its force, which is the film's way of showing that the pair now rely on each other. Mr. Paradox is jailed, and the TVA allows Logan to remain in Wade's universe. B-15 will not change Logan's past. The film ends with the two as friends, and it is left open where they go next in the MCU.
In my opinion, the shared burden is the smartest choice in the film. The Time Ripper could have been beaten by a single heroic sacrifice, the way Avengers: Endgame (181 minutes) built its finale around one costly act. Deadpool and Wolverine runs 128 minutes, and splitting the cost keeps it true to its odd couple setup, where neither man is allowed to be the lone hero. Perhaps the cleaner payoff is Logan pushing Wade back toward Vanessa, since it ties the multiverse plot to something small and personal.
The film also answers a problem that earlier multiverse stories left open. Doctor Strange in the Multiverse of Madness used cameos such as Patrick Stewart as Professor Charles Xavier to hint at other worlds, whereas here the Void, where the TVA dumps pruned timelines, becomes a real place where Wade and Logan fight alongside outcast variants. B-15's refusal to alter Logan's past is the cost that keeps the happy ending honest: he stays, but his loss is not undone.
Production context explains some of that restraint. Principal photography began on May 22, 2023, was suspended on July 14, 2023 because of the SAG-AFTRA strike, resumed in November 2023 and wrapped on January 24, 2024. A story built on two leads trading barbs in a few locations suited a shoot that had to stop and restart.
Why did Hugh Jackman quit Wolverine? The film itself starts from the fact that Logan, the Wolverine of Wade's universe, is dead, and Jackman returns here as a different Logan from another timeline. No studio or trade source gives a reason for his earlier departure from the role, so any answer beyond what the film shows would be a guess.
The saga's next release is Avengers: Doomsday, scheduled for December 18, 2026. For the wider order of events, see the Marvel timeline.
