"It would've required a supernatural intervention for him to have your
morality given his environment."
Flash-forward to when Harry is trying to explain to Hermione why Draco
doesn't share her morality (87/supernatural intervention).
Only I'd heard rumours that you didn't really survive the Killing

In fact, Harry didn't "really survive the Killing Curse" because it was never cast at him.

This is a line from the prophecy.
"Yes," Harry said, annoyance and frustration warring in him, "like I

That last part might have sounded a little odd, like he was flirting
with Draco or something.
This is the first of many lines that ship Harry and Draco for some reason.
One hand gripping a silver-handled cane which took on the character
of a deadly weapon just by being in that hand.
It's a deadly weapon because Lucius's wand is hidden inside it.
"He was in a situational context where those actions made internal
sense -"
