Hard to say. I'm from 2009. And that is possible since it sounds like the heroes are not always in the same world...

That's gonna be a headache, but I suppose it's a way to determine if there are people from my world. "Hey, do you know who Spider Man and/or Batman is?"

Well, I doubt E is dead. E wouldn't die like that. That'd be too not annoying. Helen just never dies. Ever. If her body is completely destroyed, she's just reborn. Bastion's got divine protection, even across universes. Plenty of people with stories connected to the team.
