When Jean and Lorenzo reunite back at their workstations, they’ve discovered that most of the scientists here are PhDs—experts capable of coming up with “a brain-scrambling neurotoxin” overnight. Jean shares that Petroski is an ally; he’s strong, in uniform, and is terrified for his daughter. She also notes that all the scientists are exhausted, and soon, they’ll have the lab to themselves. Lorenzo tells Jean to rest for a few hours and, while she’s at it, gives her an iPad to read up on brain science, anatomy, and trepanning—he’s busy and so she’ll have to perform the procedure on the chimp, unless they’re okay with starting on Morgan and possibly killing him.

Jean loudly asks a soldier for an escort to the dorms, and Petroski calls her over. He says he called Patrick, and he asks if he can do anything else for her. Jean tells him exactly what to do.
