A legendary discoverer comes back to camp at Terra Nova, and Maddie is thrilled to meet him.  She helps him out as an intern and realizes that the man has a terrible memory.  She thinks it is more than that, and finally figures out that he is actually the legend's assistant.  The assistant killed his boss, had plastic surgery and impersonated him so that he could come to Terra Nova.

Meanwhile Josh needs to steal medicine from his mom's clinic as his favor to Mira.  He asks for proof that she has contact with 2149, so Mira lets him talk to his ex-gf for a couple minutes.  He then breaks into the clinic, steals the medicine, and brings it to the Sixers.  He eventually admits it all to his parents.
