How much worse is it going to get for him with Grey?

Nolan has to prove himself every day in every episode why he belongs there.

But now he does.

We know John and Lucy are together, but their relationship has to be kept a secret.

But Talias already found out.

The stakes are very real and the unfairness of the stakes are also very real.

The impact on Lucy would be much different than it would be on Nolan.

We dont shy away from having that conversation.

They have to tread carefully, especially now that Talia does know.

Does Lucy tell Nolan about it?

When does she do that if shes going to?

How does he react if she tells him?

All those things are fertile ground for drama and add obstacles to their relationship.

Will we see what brought them together at the Academy?We dont really see the Academy.

We definitely touch on it, but were never going to go see it, so to speak.

Will we see her again?

How much will that inform his arc this season?We definitely see her again.

And it plays a fairly big piece [in] his story line.

Its a really dynamic story, and its really emotional.

It totally makes you rethink him in your mind.

Talia and Angela want to become detectives.

Will we see more of that journey this season?We will.

The ambition both of them have is a driving force for them.

Theres always a bit of a competition.

Not just as a cop but as a forty-something-year-old man?

How do I square who I was with who I am?

Jackson froze up during the shootout and got a stern warning because of it.

Is that going to be a recurring issue?

He has never done it before.

He never imagined he would in that moment.

That is a huge thing for him to overcome because it just came out of nowhere.

So it will definitely play a part.

Especially in the first part of the season.

Because if Lopez cant trust him to have her back, then thats a huge thing.

Will we meet his dad this season?We do get to meet him around episode 8 and 9.

How much more will we learn about Lucy and her parents?

That relationship seems to feed her a lot.It definitely does.

So far, were not meeting them necessarily right away.

Theres a lot of stuff to do there.

As Talia said in the pilot, Were not partners.

Thats both comedic and emotional.

Theres an abduction story in this episode, which is really dynamic and puts him in a powerful place.

At the same time, Lucy is stuck with a temporary training officer while Tim is on the mend.

The Rookieairs Tuesdays at 10 p.m. on ABC.
