Eureka: Hide and Seek2006

Henry Deacon:
[indicating the microscope] Um, look at this. It's the cellular structure. The DNA markers are humanoid, but slightly different than ours.

Jack Carter:
[looking through the microscope] Oh, wow.

Henry Deacon:
Do you have any idea what you're looking at?

Jack Carter:
No. Not really.

Henry Deacon:
They are regressive genetic traits that haven't been seen in maybe a million years. You'd have to be a neanderthal to still carry genetic markers like that. Oh, and here's the kicker. The, uh, the tooth that you gave me... doesn't belong to this thing.

Allison Blake:
So there's another one of these things running around?

Jack Carter:
One that eats bears.

Henry Deacon:
[holding the tooth] Yeah, and judging by the size of this, it's bigger. Much bigger.
