Y'know, I was casual. You attacked me; I stayed, you know, pretty relaxed. If you wanna read 'overbearing tone' into every single one of my posts, you go right on ahead, but you better understand that the tone is in your head, not in my writing.
And yeah, I can be absolutely certain that Marchand wasn't the first victim, and it's pretty clear I do know something you don't. Make up theories all you like, but I suggest you clear them through BOTH the 'history of the 6th World' buffer and the 'what the game designers came up with and when' buffer, because while with some things they do really leave things wide open (fates of the Big Three AI, half the stuff from Dunkelhzahn's Will, etc.) there is other stuff that they pretty thoroughly nail down. In this particular case? Brainscan, pp. 69-70, 'The Minds of Olivia Marchand'. She didn't get personalities crammed into her head, her own personality fractured.
By the by, the next time you ask 'Do you know something I don't", then answer yourself with 'if you don't, as I suspect', understand that I have been reading and playing this since the year it came out, and that people who do write for the game ask me questions, and that when posters here talk about 'people who know the backstory of Shadowrun', I'm invariably one of the first two people mentioned. So yeah, the chances of me knowing something you don't are pretty damn good, and considering that my deductions have about an 85% accuracy rate, there's a reason people listen to what I say.
But hey, nobody's making you listen to me - or take umbrage with how I write. You're doing that all on your own.
