Cosima Niehaus:
Okay. But how to decode it? I have four nucleotides to work with G, C, T, and A; and no idea how they're encrypted. I mean, there's thousands of permutations and we're running out of time.

Delphine Cormier:
Yes, but I know your tag number.

Cosima Niehaus:

Cosima Niehaus:
Okay. What is it?

Delphine Cormier:
It's 324b21.

Delphine Cormier:
324b21? [Delphine nods] Right. I'm 324b21.
