Recently it has been confirmed that the post-credits scenes in Deadpool 2 are canon. That means that Deadpool preventing the deaths of Vanessa and Peter are true, meaning the two of them are alive. It also means that the Deadpool from the original timeline is dead now. Therefore, I believe that the pages for Vanessa and Peter from the revised timeline should say they are alive, as should their status on the Deadpool 2 page as well. It should also mention on the original timeline Deadpool's page that he he dead as of the events of Deadpool 2. I just wanted to get my opinions about all of this time-travel nonsense and hope that the staff make the right decision that benefits the wiki's canonical status for their content.
