Leliana couldn't help but smile as Tariel skipped along beside her, gripping her hand without fear. His eyes lit up in wonder every time he saw something new, often stopping to point and ask for clarification. In the short time he'd been at Haven after attempting to seal the Breach, he'd wormed his way into everyone's hearts, except perhaps Seggrit's. Though Leliana was sure that sour apple loved nothing other than himself and his profits. It was at no lack of attempt on the elf's part, that was for sure.
Most of the people at Haven would put down whatever task was at hand to accommodate the young elf's questions, explaining however they could. It was a drastic change from trying to murder him not a week ago. While he was eager to learn about whatever he saw, he wasn't as interested in talking about himself, and the only thing he'd revealed to her was that he was changing clans.
"Keeper said we had too much magic," was all he revealed. Anything else he only shared with Solas, when the apostate had time. He seemed to find comfort in talking to other elves. There was very little she could learn about him, as he'd spent his life in a Dalish Clan. As frustrating as it was to find so little, eavesdropping on him and Solas or talking with Minaeve revealed that he was being traded to another clan in need of a first.
How he'd winded up at the Conclave, Leliana didn't know, nor did Tariel seem to remember. What happened to the escort was also a mystery, though she had a feeling whoever was with him died in the explosion, much like everyone else had.
Ah, trying to explain how he ended up in Haven. I figured that since Lavellan doesn't outright abandon mages, according to dialogue my Lavellan had with Minaeve, I decided that a hunter was responsible for escorting him to the clan in the Exalted Plains because… I dunno, they might have found Valorin's body and with Taven being a things in the Graves, he needs Tariel.
