Spider-Man: No Way Home - 10 Biggest Questions It Leaves Unanswered
6. Did Andrew's Peter Kill Harry Osborn?
No Way Home does a great job of filling audiences in on what happened to Andrew Garfield's Peter since the tragic events of The Amazing Spider-Man 2, where Gwen Stacy (Emma Stone) perished at the hands of Harry Osborn aka the Green Goblin (Dane DeHaan).
It's clear that Gwen's death has heavily impacted this Peter's life ever since, to the extent that he even hints to his fellow Spider-Men that he fell into habits unbecoming of a superhero.
He talks in vague terms about becoming lost to his rage and no longer pulling his punches, and while not going into any wider detail, he may be implying that he sought the most ultimate brand of revenge against his former friend Harry.
Is it possible this Peter ended up killing Harry to avenge Gwen's death? While that's perhaps not something the MCU would want to directly infer, it fits the bitter, traumatised mental state that Peter was apparently in following Gwen's death.
This is of course just a possibility, but we'll almost certainly never know for sure either way.
