"The Invisible Girl"
As the Spring Fling dance nears, Cordelia's new
boyfriend is mysteriously beaten up at school -- by a baseball bat with
no one attached to it. The attacker leaves a cryptic message on the locker,
which leads Buffy to believe it wasn't an ordinary monster. Giles suggests
it might be an invisible creature or a ghost.
Another attack finds Cordelia's friend Harmony flying backwards down a flight
of stairs, with no apparent outside force. After hearing a girl's voice,
Buffy pursues the invisible attacker to no avail. Buffy enlists Willow's
help in trying to get a list of missing kids -- perhaps this invisible girl
is one of them. Meanwhile, Angel appears at the library and says he's worried
about Buffy -- he knows that something big is about to happen but he doesn't
know what.
Shock of shocks -- Cordelia is elected the May Queen for the school dance.
Buffy is convinced Cordelia is the link between the two mysterious attacks.
She finds a girl in Willow's printout, Marcie Ross, who she thinks might
be the one. Marcie was in the band, and the invisible girl keeps hiding
in the ceiling above the band room. Buffy follows her there to find a nest
of sorts where the invisible girls has been hiding. Another attack occurs:
Cordelia's teacher is almost suffocated.
Further investigation reveals that Marcie was in everyone's classes, but
no one seems to even remember that she existed. Giles says she simply became
invisible because she was perceived that way -- it's all due to physics,
helped along by living above a Hellmouth. Marcie's goal seems to be to destroy
Cordelia, who is already wigged out by the attacks on people close to her.
Cordelia's coronation as May Queen that evening would be the perfect place
for Marcie to attack, but Cordelia is none too thrilled about being used
as bait. As Cordelia gets ready at school for the dance, Marcie yanks her
up through the ceiling. Meanwhile, Giles, Willow and Xander hear some haunting
music and try to follow it, hoping to find Marcie. The trio is led to the
boiler room where they are overcome by gas fumes. Marcie anesthetizes both
Buffy and Cordelia, brings them to the Bronze and ties them up. Marcie,
armed with an arsenal of creepy surgical instruments, explains to Cordelia
that she intends to give her a face no one will ever forget. She slices
Cordelia's cheek, but Buffy manages to free herself and a scuffle ensues.
Buffy finally knocks Marcie out, just as a pair of FBI agents arrive to
take Marcie away. Angel saves the unconscious gang in the boiler room, but
Giles tells Buffy it was a janitor -- he doesn't want to remind Buffy of
her lost love. Cordelia acts grateful to the gang, but becomes her normal
obnoxious self when her newly-healed boyfriend and her cooler-than-thou
friends show up.
