History
In this reality, Spider-Man gets knocked out during the Spider-Slayer fight, and by the time he wakes up and saves Mary Jane, she has to be hospitalized. Her life is saved, and she says yes to Peter's proposal. However he began to have nightmares that make him realize he couldn't keep Mary Jane safe and decides to back off, leaving MJ at the altar. The whole affair enraged Spidey and he violently took to the streets as an unhinged vigilante. However, crime fighting was not enough for him, so he joined Silver Sable's agency seeking more jobs. While working for her, Silver Sable had to step in to stop Spider-Man from being too anxious from time to time; though she realized that something was eating at him, she decided it wasn't her business.
Eventually Peter decided to get back together with the Black Cat and married her, but the marriage quickly failed when Black Cat's mistake revealed his identity to the Vulture and jeopardized Aunt May's life. Mad at her, Spider-Man went to Silver Sable to talk with her, he briefly went over how his Uncle died, and Sable sympathized with him, given how she witnessed her mother's death. She told him that he shouldn't let it harden him like it did her, but Spider-Man knew that she was plenty human under her colder exterior. Before the conversation could go further, Paladin busted in to tell Sable that they were needed to fight some terrorists. Spider-Man and Silver Sable ran into action. Elsewhere, the Vulture escaped from prison, only to be immediately cornered and brutally attacked. He muttered Spider-Man's name before dying. During the havoc, Paladin shot Black Cat, resulting in her death. Now a widower, Spider-Man continued to work with the supportive Silver Sable and eventually, romance blossomed between them and they began a serious relationship.
The Watcher left the future of their relationship under a veil of doubt, not revealing whether their relationship would work out or not: "...he eventually does get past his mourning and goes back to fighting crime. He meets with Silver Sable both on the battlefield and in private. Who knows whether it'll work out or not? But for the time being, Peter Parker and Silver Sablinova have each other and that's enough."
