about quotes.

[Wildcard]

It depends on how clear it is who is speaking and how it is laid out. Leaving quotes open can indicate that one person speaks over many lines:

"Verily I say unto thee,
repent from your evil ways
and keep not the ways of Todd.

Behold! Billy is the god to serve."

Or you can have multiple speakers in one line:

"Did not." "Did too!" "Did not!!"

I think it is mostly just about making it clear who is talking.
