Remember when the plot of the Hulk vs Iron Man came out and everyone got pissed because “Oh no Waid is making something ELSE Tony’s fault why can’t Tony catch a BREAK.”
Let’s talk about how fucking AMAZING Waid wrote Tony and how good of a friend and man he made him out to be and how fucking BRILLIANT this was for two seconds.
Quick Summary: Original Sin is happening, everyone is getting memories of long buried “sins”. Tony and Bruce both get a flash of the night of Bruce’s fateful encounter with the gamma bomb. Turns out Tony was there, drunk off his ass, teasing Bruce about what a loser pacifist he was and how he should leave the weapons-making to the REAL men, basically. Then, ORIGINAL SIN, what’s this? Tony got paid to tamper with the bomb? IT’S ALL TONY’S FAULT THAT BRUCE IS THE HULK?
Wait, nope. EXACT OPPOSITE ACTUALLY. Tony went in to take a look at the bomb, sure. But he realized that Bruce had put too much shielding on it, and turned it into a weapon five, ten times bigger than he had planned. Even drunk as a skunk, Tony made the decision to fix the problem for Bruce, removed some of the shielding, saving Bruce’s life.
When Bruce does his vaguely suicidal tendencies thing and ruminates how it might have been better if he had died that day, Tony actually gets fucking PISSED at him, and calls him out on it. Because Tony’s a GOOD GUY and gives a shit about his friends (even the ones he doesn’t LIKE that much).
And, the coup d’etat of this whole, glorious miniseries: the real sin, the thing Tony is keeping from Bruce at the end of it all? Tony sent Bruce an email that night. An email about how he has a suspicion that gamma radiation could change people’s shape, change matter’s form. Warning Bruce to take a look at it before the test. And Bruce blocked. Tony’s. Email.
It wasn’t Tony’s fault Bruce was the Hulk. Tony kept Bruce ALIVE. It was BRUCE’S fault he didn’t read Tony’s email. Tony might have SAVED Bruce from becoming the Hulk. And because Tony realizes this, and Bruce doesn’t, Tony makes sure that Bruce will never, ever, EVER know what-could-have-been, because he knows it’d kill Bruce.
In conclusion: Waid continues to be an amazing fucking writer, Tony continues to be an awesome human being, both presently and in the darkness of his shadier, less-than-heroic past.
