Seth led the way still in wolf form. As he came up to Alice he whimpered, but then moved past her in to the building for he had clothes that he left there when Edward treated him to a meal a few days ago and he wanted to get them for he could change. He needed to be around when Leah was looked at and he wanted to be able to talk with Carlisle and Jake about Leah. This was his sister, she was his second mother basically, and he needed to know she’d be fine. Plus he wanted to see if Leah would talk to him. He was concerned like any brother would be.
