Vague storyline that bears little in common with the actual storyline... :-)
Willow is sitting on Oz's bed, looking around his room, at the stuff left behind.
Buffy and Willow are patroling in the graveyard, talking about Riley.
Spike is chained in Giles' bathtub (!), being taunted by Buffy.
Willow had the sense to look through Giles' books in the front room and not get involved in Buffy and Spike's madness.
Spike, drinking blood, from a "Kiss the librarian" mug.
Another establishing shot of Sunnydale.
Willow has been back to Oz's room. It is empty.
Willow goes to the Bronze...
...and drinks beer. Too much beer.
Annoyed and upset, she lays the cirle in the bathroom and casts a spell to have her will be done.
Next day, Giles asks where Willow was. Willow is heavy with the pain-and-pity-me and says Giles can't see anything. Giles, suddenly distracted, stumbles out.
Willow puts the Amy-rat on the bed then goes to tidy the cage, saying to Buffy that Amy had access to power she can't touch. She's a human (poof! Amy appears on the bed) and then she's a rat (poof! Amy turns back into a rat).
Willow, annoyed, tells Buffy if she's so into Spike, she might as well marry him. So they propose and accept, much to the horror of Anya and Xander.
Ta'hoffren takes Willow...
...and offers to make her a vengence demon, as her pain is transcending dimensions.
Willow, shocked to learn what has come about as a result of her spell, declines Ta'hoffren and returns to where Buffy, Spike, Anya and Xander are fighting their last battle.
Willow undoes the spell, and sets about baking many many many cookies...
...as her form of apology.
