There was loose, bulging linoleum on the floor. marian felt
as if she were walking on the waves, but the nurse paid no
attention to it. there was a smell in the hall like the interior
of a clock. everything was silent until, behind one of the
doors, an old lady of some kind cleared her throat like a
sheep bleating. this decided the nurse. stopping in her
tracks, she first extended her arm, bent her elbow, and
leaned forward from the hips-all to examine the watch
strapped to her wrist; then she gave a loud double-rap on
the door.
"there are two in each room," the nurse remarked over her
shoulder
"two what? " asked marian without thinking. the sound like
a sheep's bleating almost made her turn around and run
back.

"There are two in each room," the nurse remarked over her

shoulder

"Two what?" asked Marian without thinking.

Explanation:

Dialogue is when a character speaks to another character. A character can speak to themselves (monologue). Marian and the nurse share one line remarks to one another, which is the only dialogue in this passage. The rest is imagery/narration.

Dialogue is identified by "quotation marks".

Quotation marks most often indicate dialogue, but do have other uses.

Such as for "Book Titles", or sarcasm.

themselves

an intensive pronoun is a pronoun that ends in self or selves, such as himself, herself, themselves, yourself, ourselves. since band members is a third person plural, the correct intensive pronoun would be themselves. if the band was talked about as a collective noun, itself would be the appropriate intensive pronoun. intensive pronouns are used to add emphasis to the noun it's modifying which is why it directly follows it.
