The greatest thing we've lost

Peter Parker was just trying to have a normal evening after his patrol - as normal as they'd been after the whole world forgot his existence. Suddenly finding himself in the middle of nowhere definitely was not on his list of to-do's, especially when it turns out he's been thrown into another universe. Another universe where he's apparently dead. At least Tony Stark was alive, even if he thinks that Peter is some hallucination.
