(Hetty walks up to the group with a shirt)
Hetty: What is this, Mr Callen?
Callen: Uh, that is a knit combed cotton.
Hetty: With a bloodstain.
Callen: I would never bleed on your wardrobe, it had to be a bad guy.
Hetty: Good, bad or ugly, I don't care. The point is you neglected to tell me about it and now it's set long enough so that it might be permanent.
Sam: Hetty, it's just a shirt.
Hetty: No, no, no, no, this is not just a shirt. This is a Saville Row one hundred percent polished Egyptian cotton hand stitched with pearl buttons. That thing you're wearing is just a shirt.
Sam: Yeah, but it's a comfy shirt.
Hetty: (to Callen) Your new color scheme is black.
Callen: I can live with black.
