Thanos was the worst thing that happened to this universe for a lot of reasons. But the fact that it created this bond between people, locking them together, may be the only semi good thing to come out of it all. Some speculate it was the soul stone's prize for letting half the universe free again. Other's say it was a curse. Peter didn't really care what it was. It intrigued him, sure. But he didn't put a lot of energy in it. He was, most of the time, happy with his life. He still had nightmares, and flashbacks of the night on Titan. Of the day he returned 5 years later. Of the time he spent in the stone. Living there. Moving on. Just to be dragged back, right into another war. Seeing Tony, lifeless and burned. He still can't wrap his mind around how he even survived that. Thank every deity out there for dr. Strange and Wanda for whatever they did.
