Very end of the fight, read this last, etc etc
As previously discussed, Adaar gets her big gray hands on the killing blow.
I think we've decided that she'll swoop in just in time to save Eddie from dying a horrific death, probably somewhere near 305? I like to think you all are compassionate enough to move the fight away from the hospital area. Adaar won't use her magic right away to avoid hitting people with spells or destroying things by ripping them up in a rift, so in order to save Eddie, she's going to tackle a bitch.
What will ensue is a big, nasty brawl while she shouts for people to get out of the way so she can do some damn magic. It probably looks cool. I bet the werewolf loses a chunk of something on her horn. Once most people are (hopefully!) out of the way, and it looks like the werewolf might actually win because she is tore up, Asala is going to electrocute the shit out of him. (See why you needed to be out of the way now?) She keeps a knife on her, so the actual killing the strike will be a knife in the throat, just in case he turns out to be resistant to electricity damage.
When she's sure the wolf is dying, she'll end up saying, "Andraste guide you to the Maker's side", and then because Octavia is the best human to ever human, Octavia will get in there and say the right thing. Because respect for the dead.
With Dawn's permission, Asala's injuries are the following: General bruises and cuts, a huge, messy bite on her arm of the he-tried-to-tear-it-off-at-the-elbow variety, and nicks on her face. She came in wearing vitaar, so any cuts on her face will be at the edges/her lower lip/her jaw, as the vitaar will protect her eyes, nose, forehead and most of her mouth. She'll lose a not-insignificant amount of blood, she'll be covered in blood, and it'll just be a big, gross affair.
Because Qunari are genetically different enough from humans to be unable to breed with them (the way humans can with elves or), and because part of that genetic difference has to do with the Qunari breeding in dragons becausewhythefucknot, Adaar will be immune to the werewolf curse, as the curse can't be transformed. And because dragons.
