Grey-Sloan
Memorial
Hospital
is
bracing
itself
for
another
major
threat.

In
E!
News’
exclusive
sneak
peek
at
the


Grey’s
Anatomy
season
21
finale,
airing
May
15
on
ABC,
Dr.
Amelia
Shephard
(Caterina
Scorsone)
and
Dr.
Simone
Griffith
(Alexis
Floyd)
are
enthralled
in
a
serious
conversation
about
Simone’s
recent
breakup
with
Dr.
Lucas
Adams
(Niko
Terho),
only
for
the
two
to
be
quickly
interrupted
as
Jenna
Gatlin
(Becky
O’Donohue)—a
patient
whose
daughter
Dylan
was
left
paralyzed
following
brain
surgery
performed
by
Dr.
Shephard—enters
the
room
carting
a
large
metal
tank.

“This
tank
is
full
of
acetylene,”
Jenna
says
to
the
doctors
in
the
clip,
visibly
shaken.
“One
exploded
at
my
husband’s
work
site,
and
it
took
down
half
the
building.”

And
as
Amelia
inches
forward
to
attempt
to
calm
her
down,
Jenna
issues
an
even
more
menacing
threat.
 

“You’re
gonna
put
your
phone
on
the
counter,”
she
tells
Amelia,
“and
then
you’re
gonna
operate
on
Dylan,
and
you’re
going
to
fix
her.
And
if
you
don’t—if
you
don’t
save
her,
I’m
taking
everyone
down
with
me.”
