The Fight
Willow woke up suddenly. "No, not sleeping, not me." She uttered without thinking as she looked round the library. A look of horror appeared on her face when she saw the cage was empty, the door broken down. Oz had escaped. Quickly Willow grabbed the rifle and ran into the night.
Oz could feel himself within the wolf, but had no control over his own actions and felt very much like a passenger in is own body. Even through this he knew where the wolf was taking him, what scent he could smell in the nose that felt strangely not his. The wolf was taking him to Angelus.
Willow raced through the night, hoping she was headed in the right direction, hoping that her instincts in what Oz would want to do if he had the strength were right, and headed towards Angel's mansion. "He's going to get himself killed." She muttered to herself as she drove herself on faster.
She was too late though. When she reached the mansion she saw Oz, in his wolf form, and Angelus already fighting, trading blows and tearing skin and muscle. Willow loaded the tranquilliser into the gun and got ready to shoot, then hesitated. She couldn't shoot Oz, and leave him helpless, but she could shoot Angelus and make sure Oz got the upper hand.
Buffy had been unable or unwilling to kill Angelus, so why shouldn't she help Oz kill him. And with that thought she pulled the trigger, catching Angelus in the neck with the tranquilliser, then stood back to watch it take effect.
Oz felt Willow there, but didn't really take much note of her, then saw the needle sticking out of Angel's neck. He knew it would make no difference, Angelus's blood didn't circulate, so couldn't carry the drugs to the necessary places for them to take effect.
Eventually Oz managed to get the upper hand though, his Were stamina managing to outlast the Vampires, and he grabbed Angel's head and pulled with all his might, pushing against Angelus's body with his rear legs while pulling with his front.
Dust filled Oz's lungs as the head separated from the body and he then turned his attention to Willow, who was now staring at him with fear in her eyes, but the wolf had had it's fill and recognised a friend in her. On all fours he bounded across to her then nuzzled into her side, and as she petted him gently he stuck his tongue out and licked her hand.
