Tony dieing is a fantasy narrative with no evidence.
And no a vague line interpreted as forshadowing isn't evidence. The fact there's a guy in a sports jacket isn't evidence. The fact Tony looked up at a ring isn't evidence either.
Stop pretending people are denying hard data. It's not. It's a flimsy theory you pulled out your arse that you're only convinced is true because it makes you sound smart, you smug, pretentious cunts.
