There

is

a

Sound

of

Music

sing-a-long

and

everybody

dresses

as

his

favorite

character.

Will

ends

up

at

the

wrong

address,

but

luckily

meets

a

handsome

guy.

Grace,

meanwhile,

feels

a

little

misplaced

as

a

Maria

without

her

Mr.

Van

Trap.

Will

decides

to

stay

with

the

guy

he

just

met,

leaving

Grace

alone

at

the

movie

theater

where

starts

singing

songs

from

the

movie

to

children.

In

the

movie

theater,

Karen

throws

her

flask

of

the

balcony,

she

and

Jack

have

to

search

for

it

before

someone

finds

out

that

it

was

her

who

threw

it,

because

her

name

is

on

it.
