Incorrect - he was "killed" first season by Sylar.
And was dead until Claire pulled the glass out of his head, so he obviously doesn't have to turn it on "while alive."
And while he was shot in the chest, it's implied, by Claire, that he was killed.
To be honest, I'm not sure.
I just recall reading it somewhere, though I'm too tired to recall where I recall reading it.
But... the story is finished... once you're a god, where else can you really run with it?
Thread pruned a little bit.
Let's focus on the topic at hand, please.
If a poster's actions bring confusion to you, you can always message them for clarity rather than trying to derail.
As for this topic: We already had a Baldur's Gate 3... it was Throne of Bhaal.
