Borden subsequently blows himself up as well, nearly taking Patterson with him.
EW turned to executive producer Martin Gero to find out.
ENTERTAINMENT WEEKLY: Patterson was ready and willing to shoot Borden.
Can you talk about how that affects her?
She says she’s fine, but is she really?
MARTIN GERO:This kind of grief affects people in a lot of different ways.
This was Patterson’s moment to show Borden that she’s better than him.
How much guilt does Patterson feel after all this?
She wasn’t the mole, it was the molar.
[Laughs] It’s a tough situation for her.
Suddenly, her job is causing her a lot of real-life problems.
At this point, did Bordenhave todie?
Yeah, I think so.
I don’t know how you redeem a character like that.
It’s a real mixed emotion for everybody because obviously it’s a character we love so much.
He went from being a shining star on our show to being truly vile.
Ukweli really played that transition so beautifully and spectacularly.
He’s fantastic and we’ll be very sorry to see him go.
How will Shepherd react to not only losing her bug within the FBI but also losing Borden?
We’re pushing toward a really satisfying ending for the season.
We finally have turned the tide a bit in this episode.
Phase 2 is going to result in a lot of loss of life.
What can you tease of the build up to this?
How difficult will this be for the team to stop?
It’s going to take everything.
It’s going to be the hardest thing the team has ever done.
When our team is intact, there’s nothing they can’t handle.
The steps that we do to get there to get to the end are [surprising] as well.
Shepherd is on a barge in the middle of the ocean.
Where is she going?
You’ll find out in episode 18!
Is she actually running or is there more to this?
No, she’s got to pick something up.
How will he react to that?
How do you know that’s happening?
Because thathas tohappen at this point!
It’s the moment we’ve been waiting for all season.
Well, you could wait a little while longer.
Zapata has seemingly revealed the truth about Reade’s drug problem to Weller.
How will that shake up the team?
It’s really rough on them.
That’s a friendship that’s been tested a lot this year.
Reade is in a really rough place.
He’s definitely not going to be thrilled that Zapata has [ratted] him out.
How will Weller handle that?
It’s the next episode, so you’ll see.
The episode closed with Jane and Oliver being drugged.
What can you tease for what’s next?
Might this have to do with Oliver, not Jane?
Yeah, I think the twist there isI will tease it outnot what it seems.
There are layers of complexity to Oliver that we have yet to find.
Jane’s initial reticence to maybe not trust him was probably right.
