Arya slipped off of the horse, not ungracefully, but still breathed a sigh of relief once her feet hit the ground. She had no idea who these people were, but everyone seemed quite busy checking on everyone else - a good opportunity to walk away. Then again, perhaps it was unwise to continue wandering through the forest as she had, all on her lonesome. If these people hadn't arrived when they did, well, there would be one less Arya in the world. Not to mention that there would probably be more darkspawn, and if there were, they might be attacking her brother's clan. One elf against even a small horde was certain suicide.
Contrary to popular belief, she had no idea who the other elves were on the side of the clearing, though one of the group of rescuers clearly did. The markings on the newcomers' faces made it clear that they were Dalish, and if that were the case, perhaps they knew more about her brother. This was perhaps turning out to be the meeting she'd hoped for.
"Thank you," she turned and gave the quick mention to the red-headed girl, a weak response for the girl's life-saving efforts, and began to move towards the elves. There was a reunion of sorts happening, and though she was loathe to interrupt it, she wanted to know what they knew. If Terin was alive, if he was all right, if she could see him. This, of course, all rested on the thought that they even knew her brother, but she couldn't douse the hope that was beating in her chest.
