CalamityRanger: *spoilers*
Oh, another thing I enjoyed: During the fight with Meredith the people you've helped along the way just show up and start fighting with you (I like it a bit better than DAO since you don't physically summon them, they come out when they want and just join you in battle). I smiled cause it seemed like Aveline and Donnic often targeted the same creature in the points where Meredith wasn't around. :)
We might have to make a proper DA2 thread now as the spoilers are coming thick and fast :p

While I did like that Zevran and the others turned up I thought it was done a lot better again in DA:O. Who joins you in the fight with the Archdemon depends on who you aided and talked to in the game. Irving, Tegan, Eamon, Kardol etc all turn up to help if you helped them. I don't know for sure but I would put money on Zevran turning up at the end of DA2 even if you didn't bother with the quest to meet him. DA2 just has that vibe about it that nothing you do actually seems to matter.
As for Gascard it's worse than you think, there is a chance he will JOIN the serial killer despite what he did to momma Hawke. If you are going to play the game again take Varric with you. He sees through Gascard far quicker than Hawke does apparently.
Namur: Why would one of his teams go reclaim the mage, what difference would it make ? Isn't Aarvard or what's his name one of his teams already ?
Hawke spent 'alone' time with a mage who was cut off from the Qun, that means either death death or ceremonial death, the end.
When I say reclaim, I mean go and kill. Quite frankly I had Bethany next to me at the time so had bugger all interest in helping the Chantry/Templars and the Qunari seemed to be the only people in Kirkwall whose word actually meant a damn. Ideally I would like to flip her the bird, go straight to the Arishok and say "Dude, some Chantry bint has one of your pets in Lowtown. No one knows she is there so if you want to kill her it's cool."
