History ComicBook / OneMoreDay

* RelationshipResetButton: The marriage of Peter Parker and Mary Jane is canceled by a deal with the demon, and Peter returns to [[SuperheroesStaySingle be single]]. He forgets all about it, but Mary Jane remembers.

* ProtagonistCenteredMorality: Parker commits several questionable things while trying to save Aunt May. He blamed and attacked Tony Stark for it because Stark promised she would be protected if he signed the SHRA (ignoring that went rogue, removed them from the tower, and forfeited that protection), he stole a dangerous artifact from Dr. Strange to SetRightWhatOnceWentWrong, and he made ''a deal with the devil'', even against May's own wishes.
* TheReasonYouSuckSpeech: Peter's possible child in the future gives him a scathing one calling him out for his selfishness and putting his pain ahead of everything else cause it makes him feel bigger. Worse still Peter Marvels, if not all of media's, biggest wise cracker, doesn't have a real answer, rebuttal, or even a decent quip ready to counter her assertion.

* CosmicRetcon: Peter makes a DealWithTheDevil erase his marriage with Mary Jane in exchange for saving his Aunt May's life. The entire purpose of this arc was to retcon the Spidey marriage.

* ContinuityNod: The final panel toasting to the Brand New Day (basically a bunch of hands carrying glasses raised high) is similar to "The Wedding!" (''Amazing Spider-Man'' Annual #21). It is a snide inversion and swipe of a panel image in Annual where Peter, Harry, and Flash raise a toast in celebration to Peter's nuptials (three hands raising glasses above). In the wedding one, Flash Thompson raises the toast after cheering and clearing up Peter's second thoughts and insist he go ahead with getting married, insisting that it's the best thing that will happen to him; it is reused in the new story for raising a toast celebrating the single life.

* BrokenAesop: Breaks the [[WithGreatPowerComesGreatResponsibility aesop]] that ComicBook/SpiderMan is supposed to embody, as instead of taking responsibility for his actions, he dodges it by making a DealWithTheDevil against the wishes of its main beneficiary and guilt-tripping his own wife into going along with it. However, in ''ComicBook/OneMomentInTime'', this is retconned so that ''Mary Jane'' is the one to have made the deal. For readers, rewriting history just to save the life of a single person who, in addition to wanting to die anyways and was telling you to let go, and is, let's face it, likely to die of old age in a few years anyway is simply asinine. The message then becomes "the ends justify the means", and that instead of learning how to cope with loss and move on with your life, you should hold on to what you have and never let go, even if the cost of doing so might be too high; for you and others.

* CanonDiscontinuity: Despite Joe Quesada's explicit claims that Spidey's unmasking in ComicBook/CivilWar wouldn't be undone via a "magic retcon", one of the effects of the deal is that his unmasking was written out of history... with magic.

* ProtagonistCenteredMorality: Parker commits several questionable things while trying to save Aunt May. He blamed and attacked Tony stark for it because he promised she would be protected if he signed the SHRA (ignoring that went rogue, removed them from the tower, and forfeited that protection), he stole a dangerous artifact from Dr. Strange to SetRightWhatOnceWentWrong, and he made ''a deal with the devil'', even against May's own wishes.
