It didn't take him more than a minute to take in the scene. The drink, that was entirely for comfort rather than effect; Erica clearly expecting Cora, not him. Maybe he shouldn't have followed her, but despite everything that had happened back at home Derek had made himself her Alpha. As much as he wanted to ditch the title and never go there again, he knew he had a responsibility to this girl. One that went beyond whatever differences there'd been in the Pack.
"You're not fine," he said as gently as he was able and moved further into the room. Derek didn't want to crowd her or force her to open up, but he was happy to listen. "I can smell the fear, Erica," he told her as he took a seat and cocked his head her way. "I wish you'd told me things were this bad," though he didn't blame her for wanting to keep the nightmares to herself. He wasn't entirely sure Erica would have told Cora, if they hadn't been roomed together.
"So, how are you really doing?" he asked with a small smile.
