Cute Poison

Plot

Michael is three days behind on his escape plan, hindered by his new insomniac cellmate Haywire, who takes tablets to stay lucid but escapes when doctors leave, calling them "invisible handcuffs." Haywire notices Michael's tattoo and sees the hidden maze in it. Meanwhile, Veronica Donovan meets with Nick Savrinn from Project Justice, who wants to assist; they question Lincoln about the evidence, which he insists was planted. Sucre learns from his cousin Hector that Maricruz is now with him, but after contacting Maricruz, he discovers Hector lied to keep her away.

Sucre urges Michael to get him back into the cell. Michael obtains two chemicals and uses them to corrode a pipe under the infirmary. He returns to find Haywire has drawn his entire tattoo and ponders the pathway. Michael injures himself to have Haywire taken away before the plan is exposed.

Sucre is transferred back to Michael's cell, and they continue the plan. Agent Kellerman suspects Scofield may try to break Lincoln out and orders his transfer the next day.
