So, I just read Anna S.'s "The Other Half" again, because it's one my favourite stories in any fandom, and I get withdrawal symptoms if I don't read it from time to time.
Does anyone know when it was written?
Because there is that one passage that describes Absolute Power Daniel so perfectly, but I am not sure if it wasn't written before AP aired for the first time:

"You'll treat me as a friend for as long as you wear that," he said. "No more."
Voice even, gaze steady as a soldier's.
He could assume command, I realized then. And I felt like I was looking at someone else for a moment, at a man who could order a surgical air strike without flinching, kill a city without mourning. He'd talk about their ethos after they were gone, study their dead languages and burial stones, and nothing would touch him.

Which got me thinking: are there any indications that Daniel is able to act like AbsolutePower!Daniel in the episodes before?
I never thought that AbsolutePower!Daniel was out of character, no, it was frighening how easy I could believe in that version of him. So there must be something that gave me the impression Daniel could act that way, be that person.
I feel like there is something, but I can't think of it now. I really wish I had brought my Stargate DVDs, all of them, and not just the two I have here. Surely someone has theorized about this before?
Any essays or links I should know about?
Can anyone remind me of scenes that indicate Daniel could act that way?

The only thing I can think of right now is the scene in Bloodlines where he shoots the tank with the symbiotes, but there are so many explanations for that act that it doesn't really count.
Hm. Ideas?
