Heaven and earth knows no fury like a spoiler-sufferer’s scorn. When one man was targeted online to be the victim of Avengers: Infinity War spoilers, he hatched a plan to begin a year-long revenge quest against his tormenter, ultimately spoiling Avengers: Endgame in return.

*WARNING: Spoilers for Infinity War and Endgame to follow.*

Reddit user Jus10Sch was excited to see Infinity War last year. He waited months to see the movie. Before its release, he posted to Instagram how pumped he was for the crossover event, but then a total stranger flew into his comments at random and posted the names of every person who died in the movie. Our hero was devastated, but then his devastation gave way to a deviant plan of his own.

Here’s what happened next, in the man’s own words:

I messaged the guy and told him that I had already seen the movie, but that was a good prank. It was then that we became “friends,” So for about 7 months, me and him messaged each other, texted memes, talked about movies, and stuff like that. (Keep in mind the friendship was fake, I was just trying to get his trust and make him comfortable with me.)

Skip forward to about last week.

I bought my Endgame tickets and I was going opening night. I asked him if he was going opening night and he said no, which was great news. He said he was going next week (this week.) So I saw Endgame, and while I was in the theater, I took PLENTY of pictures. I took pictures of Thanos death #1, Captain Marvel, Ronin, Black Widow’s death, Smart Hulk, Fat Thor, 2 Captain America’s, 2 Nebulas, Stan Lee’s cameo, all the snapped coming back, Iron Man’s death, and several other plot points.

When I got out, I almost thought of not doing it. I don’t like to spoil movies, I think it’s lame, but I reassured myself that this guy deserves it.

So I texted him that I saw it, he asked how it was and I told him it was great, he told me not to spoil it, and I said “Oh, like how you spoiled Infinity War.” “Then he switched moods, he was all like “Hey man, that was a long time ago, we’re friends now,” Stuff like that. Then, in one glorious action, I sent all the pictures as fast as I could, messaging plot points along with the pictures.

It was all over in like 30 seconds, but he definitely saw it all. He cursed me out, saying I was a horrible person and stuff. Then he said “Why would you do that, we’re such good friends?” And I texted back, “we’re not friends, a year ago you picked me out of a crowd of thousands and ruined a movie that I had been wanting to see for months, since then I’ve been lying to you, deceiving you and gaining your trust all for this moment. You are not my friend, just a person who got what they deserve.” Then, he cursed me out some more, and I haven’t talked to him since.

Holy smokes. A) This is terrifically evil. B) We respect the commitment. C) We’re not sure if anyone totally deserves this kind of insane retribution. Admittedly, though, the chance to drop a line like, “Oh, how you spoiled Infinity War?” after a full year of waiting had to feel pretty incredible.

Online response to the revenge spoiler has been mixed. A few people think the story is fake (how could someone have evaded the wrath of their fellow moviegoers while taking so many pictures in the theater, and how could they have been so quick on the draw with their camera in a movie they haven’t seen?), but others are praising the man’s actions for its bonkers, maybe sociopathic level of determination.

There’s a Ron Burgundy meme to be referenced here: We’re not even mad, that’s amazing.
