ENTERTAINMENT WEEKLY: You introduce a new character, non-binary substitute teacher Cassidy Geoffrey.

But it’s something we learn from context clues like an “Mx.”

It wasn’t about their identity.

And so the teacher’s the same way.

OnAbbott, we don’t think that everything has to be a big teachable moment.

It’s just letting those people exist in the world.

Melissa jumps to conclusions about them.

Is that because of unconscious bias or just truly missing Janine and their hijinks?

Just that she’s missing Janine.

People are scared about having queer and trans characters that are flawed.

That’s the way of the world.

The substitute teacher in the situation isn’t bad.

They just have their own methods that might run other people off.

If we took out those quirks, it wouldn’t be funny.

You have this big breakup between Jacob and Zach.

Why was it time for this relationship to end?

That certain throw in of person is someone that doesn’t cause problems but solves them.

Is the breakup going to hold?

People make up all the time.

At least for this season, that relationship is over.

You never know how long the show will go.

I wouldn’t completely kill the door on that relationship because truly you never know.

He beats around the bush around certain things because of not wanting to hurt people’s feelings.

That’s not how breakups are in real life.

We’ve seen Gregory and Janine as single folks.

What does a single Jacob look like?

Well, he’s single.

I’ll say that.

Rarely do Barbara and Ava see eye-to-eye.

What was the impetus for giving them this unexpected point of connection?

They don’t really see eye to eye a lot of the time.

How do they approach these situations?

Because they still approach them differently.

Was there any concern it was too far?

You finally gave Sheryl a chance to show off her voice.

We didn’t lead with the idea of having Sheryl sing.

I think Quinta chose the song.

It’s just a song that Quinta likes.

Will we get to hear her sing again in the future?

Oh, I’m sure.

She sang last season a little bit.

She was singing “Happy Birthday.”

So I think we’ll continue to find these organic ways of having her sing a little bit.

Can you tease the next episode?

The guest star is amazing.

There’ll be some fun moments to look back on once we reveal who it is.

People will be shocked to see.

It was almost given away so many times.
