It would never be clear to Willow why, or how Oz changed, but she finally thought she figured it out. The gang was home, Kennedy was in the bedroom being tended too by the other potentials, and Oz was sitting on the couch. He had many scars and many bruises, but otherwise he was still the same Oz. Willow sat down next to him, staring off into nothing.
"I just don't understand it," she started, she finally turned her head to look at him.
"I do," replied Oz, almost in a whisper. "Your friend, Kennedy, we get each other. You know? I know that sounds weird, but I could feel it. Under all that fur, I dug it. You care about her, so I care about her. You care about me, so she cares about me. Something like that," he said, looking at her and watching Buffy walk in the door. Before Willow could reply, she also turned to Buffy.
"Hey guys. So, Oz, I need to know how long you're going to be around. Not that, your in a hurry to leave, but there are some more girls coming," Buffy said, unaware of what happened. Silence. "Well, just let me know uh....some time," Buffy said before heading upstairs.
"I think I get it," the witch replied, and took Oz in a long emotional hug.
Everyone knew it was just a visit. They couldn't baby - sit the werewolf forever. Sure, Oz could stay for the long battle, probably die, but hey, if he could get out while he still could it was worth it. All the potentials begged him to stay, however both he and Willow knew this "vacation" was over. Oz packed his things, (not that he ever unpacked) and stood by the front door surrounded by everyone. Even Kennedy, who instead of frowning at Oz, actually smiled.
"Next time you fight a werewolf, come and find me. That is, after you know - the full moon and stuff," Oz said to Kennedy, and this time when he extended his hand she shook it. Willow smiled. "Take care of her."
Kennedy smiled again before Oz slipped through the door. "I will."
