Theo/Sirius.
Interesting. How'd you figure that? Is this, perchance, not your first time playing with alternative realities?
I feel compelled to confess that I am, in point of fact, very nearly charmed by your hesitance to reveal the full scope of the tragedy that awaits me should I return to it. Probably all the way charmed, actually, given that I'm amused rather than irritated at the implication that twelve years in Azkaban for murdering my two best mates is 'wonderful'.
I wouldn't trouble yourself too much, mate. I don't plan on it being the future of the Sirius Black you have before you.
