HERES WHAT you’re gonna wanna KNOW:Watch24: Legacy.

It takes place in one day oh you know this already or you wouldnt even be reading this.

Catch up on Hulu and the FOX app!

CTU knows if they can find Andy and Carter theyll find the terrorist ring-leader Jadalla.

Andy and Carter lay in the back of Jadallas van.

Nicole begs Isaac to go back for Eric.

Andy plugs in the flash drive to recover the data.

This rugged, out-in-the-field look is actually kind of working for me, uh, I meanhim.

Pretty immediately, Andy cringes as he triggers the virus, anticipating his certain death.

But Jadalla reassures him and smiles: Im not going to kill you.

The flash drive was a decoy.

Andys bravery has kicked into fifth gear.

He tells Jadalla he will NOT help recover the files.

To which he gets the very impolite response of an ENORMOUS knife in the leg!

Jadalla TURNS the knife.

Andy, in complete agony, must finally give in.

(We did that scene so many times Ive never screamed so much in my life.

Im not that familiar with torture beyond a bout of heavy whining from my kids.)

John reluctantly gives the go-ahead.

But he finds his wifes ease with enhanced interrogation off-putting does he even know this woman?

Despite the discomfort, Henry Donovan is unwilling to give up any information so they up his dose.

John struggles to watch.

The Secretary of Defense discloses a plan to Mullins, which involves a drone strike to Jadallas warehouse.

Mullins struggles to agree, not wanting to kill Carter and Andy in taking out the terrorists.

But its clear this collateral damage could mitigate the threat of thousands dying.

Mullins orders Mariana to proceed with the plan and she struggles with it.

But eventually, her finely manicured finger hesitates just a beat before finally hitting the button.

Isaac insists Nicole stay back with one of his crew.

Carter, in the warehouse, recognizes one of the terrorists as Naseri.

He calls him out but is silenced.

There seems to be some history there and this Naseri does NOT want it exposed.

She warns him of the DOD plan.

Andy screams out: Carter!

This place is about to blow!

And with that, hes able to save everyone from the explosion as they all scurry out.

Isaac gets shot in the back as they make a run at escape.

Within seconds of Carters escape, the missile hits.

Who knows who survived?

From the smoking rubble, we see Carter and Isaac are still alive.

They finally have Jadalla in custody.

And now the U.S. knows that Naseri is on their soil but who is he?

And how did he escape??

They have Jadalla in custody.

Carter and Andy may very well be dead.

Rebecca lets John release his father.

But will John ever look at his wife the same?

I did it, Tom!

Andy is relieved to see a friendly face and to have recovered the list of sleeper cells!

Hes a hero after all.

I mean, who doesnt like THAT ending?

HERES WHAT YOU COULDNT KNOW (cause it happened behind the scenes!

The harshness of torture, sure.

But equally challenging was the constant re-spray of glycerine to refresh the look of sweat.

Also dirt makeup to make us look ragged.

The knife handle was secured to a metal holder inside as well.

It was creepy and upsetting and very cool.

Jadalla pistol-whips him in the face, which caused the bloody forehead you mysteriously see in the episode now.

He then threatens to cut off Andys ear, which is just before Isaac and his men storm in.

The battle with Isaacs men we had a huge round of safe explosives that were set off.

In addition, all the guns were shooting blanks.

So it was as close to real gunfire as Id ever want to be.

They were supposed to be on some video conference call.

In reality, Black was put in a tiny room (i.e.

a supply closet) dressed as a conference room and asked to look into a tiny camera.

It was a few feet from Mullins and yet, they never really saw one another.

Ah, the magic of pulse-pounding TV.
