I have known Will for years. Trust me on this.

There's another possibility... that the man we have in custody is not Will Tippin. Project Helix. The doubling prototype that you destroyed in Poland was designed to reshape a person's physical attributes to identically resemble someone else. The prototype's database revealed two scheduled recipients of the procedure: Dr. Markovic who was killed, and a second unknown individual.

You think Will is the double.

We found Provacillium in Will's car. It's a medication usually taken by gene therapy patients to keep the body from rejecting the DNA mutations.
