Cordelia returned the hug with ease, also mindful of his injured hand. She'd been around the hero types more than enough to be able to easily side-step and work her way around most any injury, so really this was a relatively easy one. Much simpler to hug him with a hurt hand than, say, a gaping chest wound like Angel tended to sport back in his vampire days.
"Thanks," she replied softly as she released him. "I know that both this place and I wouldn't be the same without you." There was a brilliant smile on her face, softened by the words he'd spoken. It wasn't often that Cordelia allowed her carefully constructed shields down long enough to really have a heartfelt moment with someone. It just wasn't her style. For him, though, she would. Because even though Cordelia had been an only child, and even though she'd never really felt much urge to have siblings, if she did have any, she'd want them to be like Peter and Nathan.
A heartbeat passed before she glanced toward the kitchen door. "Well, I haven't heard a commotion, so I'm guessing she didn't try to leave," she commented, her gaze going back to Nathan. "We should probably lock up and head on upstairs. Knowing my luck, there'll be some emergency at the crack of dawn and trust me, my hair does scary, scary things without much sleep."
