Oz is checking the cheerleading trophy and Willow asks him if he enjoyed their date. He says yes. But, then Willow makes excuses and goes to talk to Buffy. This jock Larry comes up, makes a comment about how hot Buffy is. Then he asks how much Oz is getting from Willow
Meanwhile, Willow is complaining to Buffy about how Oz has made no moves towards kissage. The subject of Angel comes up. Classic line happens with Willow: "I'll give Xander a call. What's his number again? Oh, yeah! 1-800-I'm-dating-a-skanky-hoe!"
Cordy and Xander are making out in her car at lovers lane; he complains about Willow and Oz and what she sees in him. Cordy gets upset because all he talks about is Willow. She tells him to shutup and make out with her. They do. Xander thinks he hears a noise. All of a sudden, they are attacked by a creature on the roof. Cordy steps on it and they get out of there.
The next day, the gang inspects the car. Giles shares that there have been animal carcuses found. Willow becomes freaked. Oz comforts her. They find it odd that the werewolf was out the day before the full moon, not the full moon.
The gang is forced to take a self defense course. Larry hassles a girl named Theresa and Buffy comes up save her. Willow reminds Buffy that she's supposed to act weak. Larry is Buffy's partner, and he makes a move on her. She flips him over. Way fun!
Giles gives the gang a long boring speech. And, miraculously finds one of Xander's jokes... funny! Buffy guesses that it is a guy. Xander calls for silver bullets. Giles say no because it is still a human.
Buffy and Giles go werewolf hunting in lovers lane. Buffy finds some gossip and Giles urges her to look. She goes off and is caught in a net by a hunter. Giles comes on the scene and demands that Buffy be let go. He lets her down and introduces himself as Kane that he intends to find and kill the werewolf. The guy doesn't believe they could ever capture the werewolf. He explains that werewolves sense sexual heat and go after it.
Theresa (from gym class) is walking home and senses something is out there. She runs into Angel. He introduces himself as a friend of Buffy's and offers to walk her home.
Buffy and Giles go to the Bronze, where sexual energy is definitely present. Willow and Cordy talk and they vent on each other. Suddenly, the werewolf appears. As Buffy and Giles arrive, they see people running out. She goes in and the place is deserted. She searches in the back for the werewolf. It runs out at her and she tries to take it, but it escapes through a window.
Angel takes Teresa into an alley and kills her. The werewolf comes up and finds the body. The two bear their claws at each other and Angel finally backs off.
Buffy and Giles return to the woods and stake it out in a car. Buffy turns on the radio and they hear a report about the death of Theresa.
The next morning, the werewolf is asleep in the woods and transforms into it's human form... which is Oz.
He goes home and calls his aunt. He finds out that his cousin is a werewolf. He was bitten by his cousin.. and hence is now a werewolf. He goes to school and feels very strange.
The gang is in the library talking about the werewolf. Oz comes in and Buffy tells him about Theresa. Xander resolves to find the guy who is the werewolf. Xander brings up how he remembers his hyena experience and he can find the guy. He thinks it Larry.
Xander goes to talk to Larry. He find him in the locker room and he tells Larry that he understands what he's going through. Larry looks at Xander and comes out of the closet! He says he feels so comfortable telling Xander knowing that he went through the same thing. Xander tries to get out of it, but he can't.
Willow can't find any suspects other than Larry and Buffy. Willow feels bad about Oz and how he's really confusing her. Buffy encourages her to make a move. Buffy goes to her locker and meets with Xander. She asks about Larry, he avoids it and basically says that he's not the werewolf. They go to the funeral home to see Theresa cause Buffy thinks it may not be a werewolf
They investigate and find that Theresa was killed by a vamp. Buffy signs the guestbook and Xander consoles Buffy during her guilt fest. And suddenly Theresa rises as a vampire. She gives Buffy and message from Angel and Xander stakes her. Buffy gets up and they hug. As the hug ends, Buffy gives him a look. (classic b/x moment!)
That night, Willow heads to Oz's house. He is inside planning to chain himself up. But, she comes and demands that he explain to her what has been going on. She goes way assertive and he says he's going through changes. She notices the chains and he goes through the changes. He falls behind the couch and behind the couch. When she approaches it, he jumps out at her. She runs away and through town, while he chases her. She makes it to the library and tells Giles and Buffy that the werewolf is Oz.
So, the gang gets the tranquilizer and goes into the woods. They find him and Kane is standing in front of him with a gun that has silver bullets. Buffy tackles him so that he can't shoot. Then, Buffy starts battle with Oz. They fight and he knocks Buffy aside. Willow grabs the fun and shoots Oz. Buffy convinces Kane to leave by bending his gun in half and telling him to scram.
Xander says that he doesn't no how to "look at him anymore". Buffy says to give it time. Buffy's talking about Oz, Xander is talking about Larry. They see Larry and he actually helps a girl out. Then, he comes up Xander and thanks him. Xander avoids it.
Willow goes to talk to Oz the next day. Oz has to lock himself up during the full moon and she appologizes for shooting him. He appologizes for almost eating her. He thinks it would be best for him to stay away, but she doesn't want it that way. They end on a happy note. She almost walks away, but comes back and kisses him. And he says "a werewolf in love".
