Ariana Kane:
Who is Steven Haladki?

Jack Bristow:
He was a CIA agent loyal to Irina Derevko.

Ariana Kane:
Whom you murdered. We found brain matter in the gun you fired on the day Emily was murdered. I admit, I thought DNA tests would prove that you killed her but instead they proved you killed Haladki.

Jack Bristow:
We had reliable intel that Derevko was accessing information through the CIA. Her source turned out to be Haladki. He was crucial to her operation and had to be removed.
