If the player picks option B as their final mission, Franklin will hunt down Michael and kill him even if he chooses to rescue him from falling.
After Michael's death, some players believe that if they go to his house at exactly 1:23 AM, they would be able to see Michael and hear him talking about how he should have killed Franklin. The myth is unlikely and is most likely a result of modifications.
Currently there are no serious videos investigating this myth, and there are also no credible pictures, since all of them are the result of modifications. Unfortunately, the credibility of this myth was brought down further by clickbait YouTube videos regarding this myth.
