Sam and Kensi in “Unfinished Business”

Sam

Kensi, I know what you're going through. I've been there.

Kensi

I watched Jack...slip away. Maybe I didn't try hard enough.

Sam

I don't believe that for one minute. I know what it's like to have someone I care about come back from deployment a different person.

Kensi

After all that Talbot's been through, I'm going to do everything in my power to help him!

Sam

Kensi, Talbot's not Jack.
