Avery

From TV show<transparent>

So, they're at a wedding, two women are getting married. They're doing photos. A lot of family memers. And Sarah(onf of the brides), asks the rabbi to get rid of her binder. And the rabbi asks the organizer to hold it for her. And the organizer says this:
That's right, Avery said no binders, so no binders it is.
This is where I'm confused, because her name is not Avery, and there is no one called that name, I don't know what he means.
Thank you.

Presumably there's another character called Avery in the series, but maybe not in this episode.
