Forensic scientist, Zenigata and others in “Unfinished Business”

This is a "survival knife". It's used by special forces.

Special forces...

[pointing to an engraving on the knife] Look at this.

Hmm, it's got an engraving.

Yes. It's the serial number of the soldier who owned it.

I see. [He dashes to the door] Thanks a bunch. You've been very helpful.

I see. The gold robbers were special forces.

Yeah. No doubt.

[taking the knife] Still, he's not very bright to drop it.

Now, shall we go?

Right.

W... What do you want?

Huh? I thought I heard voices in here. Is everything OK?

N... No, I'm just mumbling to myself. What do you want?

Oh, right, right. Could you give me back the knife?

The knife? [He fumbles around for it] Knife, knife, where is that thing...? [Jigen's arm emerges from behind Lupin's coat with the knife] Oh, here.

Ah, thanks. [He stands, wondering why the forensic scientist just grew a third arm. Lupin hastily shoves him out the door]

You got what you wanted, so get out and let me work! [He shuts the door] Phew. That was a close call.
