"Me too," Sam agreed, with just the very hint of a smile. It didn't quite reach his eyes, but it was genuine all the same. There was nothing quite like the adrenaline rush of a fight, the way that it made his mind empty completely of anything except focus on the present moment. Sparring didn't come with the additional satisfaction of making a difference by saving someone's life, but he didn't need that right now. He just needed to be completely worn down, so that he could fall into bed and sleep peacefully, rather than endure a restless, sleepless night. He needed to be too tired to think.
He wasn't there yet, but he was getting there. If sparring didn't quite cut it, he would get on the treadmill and run until his legs nearly gave out from under him. He wanted to get to the point where he should have used the elevator to get back to his room, but forced himself up the stairs anyway by sheer strength of will. It was going to happen, one way or another.
Straightening up out of his fighting stance, he took stock of his physical condition. There was no shortage of aches and pains in his body, from this fight and the one before combined, and his muscles were starting to protest even with the adrenaline still running through his veins. But the sensation was good, it made him feel alive. He tasted blood, and raised one hand to a bruise forming on his jaw, which was definitely going to be tender in the morning.
Much more relaxed than he had been before the fight, he went for his own water, and took a deep pull from it. As he lowered the bottle, he nodded, and then swallowed before answering Daryl's statement. "Anytime. I'm always up for a good fight."
And it had been a good one, by anyone's standard. Even when he wasn't reeling from something, Sam had plenty of stores of anger to draw upon and channel into a fight, and it seemed like Daryl had plenty of motivation to work with, too. Daryl apparently had some kind of a reason to need the fight, too, but Sam appreciated that he hadn't asked any questions, so he was just fine returning the favor.
"Wouldn't mind teaming up either, if it came to that," he said after a moment. It was relevant because Daryl had already hunted with Jo once, and Sam had even less reason to protest an alliance when their team's numbers had just been cut practically in half. There wouldn't be any harm in extending the hand, metaphorically speaking. If nothing else, it was a way of acknowledging the other man's skill. "You're pretty damn solid."
