Oh, I'm not arguing this. Rather, I'm disputing Leaguer's specific hypothetical of "is it impossible that Maric could have impregnated Goldanna's mother and her and the baby died?" Apparently they are postulating that that event could have happened as a separate event alongside Alistair's birth as Fiona's son.
That said, I have to say I don't understand what the scenario would be for anyone to feel it was necessary to send away Goldanna's mother and Goldanna's sibling, while keeping Goldanna around. If you need the mother and baby to conveniently vanish so they can be presumed dead, and you're not in the market of actually killing them, seems like it would be far easier to send the girl away with them. You're right, who is going to believe a common homeless girl? On the other hand, why keep the common homeless girl around anyway?
I get what you're saying. It's quite possible they planned to make a switch with Goldanna's sibling and by luck, the mother and baby died and it just made their ruse all the easier. Goldanna is of little consequence either way. She was an uneducated, commoner who was young and naive. They most likely patted her on the head, gave her some coin and sent her on her way. There would be no need to prove anything to her. She most likely saw the coin as a way to shut her up and if she was as annoying in childhood as she was in adulthood, I don't blame them if they did do that. I don't think Maric got Goldanna's mother pregnant and there is some other child floating around out there, or that had died. In my opinion, it doesn't tie anything together at all, instead it just leaves the question of: Who cares about some serving girl that no one will hear about again, apart from some two-minute mission? The story is of Alistair and Fiona's connection, Goldanna and her mother are just a smoke screen that has already blown away because the real story hadn't been ready to tell. Well, that is my two cents, at least.
Of course, I am just speculating as everyone else is. I don't know what DG has planned for the storyline. It may be something entirely different and I am talking out of my ass(I have been known to do that.) All I am stating is there is a possible explanation for it. There are several. Some people seem to think that because it wasn't alluded to in the game, it can't be possible. That is what I am calling BS on. Events that happen in the novels and DLC still happen, whether your character is privy to them or not. Having knowledge of the book and the game, it kind of makes sense. It's also nice to see why Duncan was so concerned with Alistair, knowing that he promised both Fiona and Maric that he would keep an eye on him.
Honestly, I don't even know why people are so up in arms over it. As I said before, people are acting as though Andraste is his mother and she hatched him from a dragon egg.
