My theory is that the female defenders of the village were accidentally slain by Teagan. I imagine the conversation went something like this:
Mayor: So, errrm, Teagan, while we appreciate your help, we need you to...ermmm...
Knight: defend the defenseless, last line of defense!
Peasant: preverse the noble blood line!
Mayor: yeah, uhm, both of those things. So get into the Chantry and defend and stuff.
Teagan: well, I could try and build another barricade.
Mayor: no, no, that's fine, we got it covered, into the Chantry.
Teagan: But they won't attack during the day, I can help.
Mayor: Best to be safe in case of a sneak attack, yeah, that's the ticket.
Teagan: Okay, that makes sense, I guess.
*Teagan walks off*
Mayor: Thank the Maker that chump is out of our hair.
Knight: Aye, cannot believe he accidentally killed all of the female fighters. Obviously, all the awesome in the family went to Aemon.
This belief is further backed up by the fact that if you don't defend the village, Teagan is the only survivor, having killed most of the people in the Chantry while trying to defend them, and, in so doing, convinced the undead that he was on their side, and hence, left alive.
No. Isolde is Orlesian, and Arl Eamon took a lot of heat from Maric and others for wanting to marry an Orlesian woman and making her an arlessa. If I recall my codex right, she was the daughter of the Orlesian lord who controlled Redcliffe during the occupation, and fell in love with Eamon the defiant freedom fighter during the war.
Yup, and while we love to hate her, I think in a lot of ways, she draws more flack than she should. For example, swap the kid with Duncan and her with Alistair...I could see much the same sort of thing happening. And, for that matter, if the PC chooses to take a trip to the tower to get Lyrium, well, a lot of bad things could have happened before the PC got back, so the PC could easily be as stupid, without even being able to plead family.
If she had a sexy Leliana voice instead of the Teagaaaaan thing...
