Stick to the Plan (Bob)

Summary
After getting the box back, you encourage Mark to stick to the plan after he entertains the idea of opening the box. He acts terminally ill and a security guard (Bob Muyskens) takes sympathy and gives Mark his cell phone. Mark calls Bubba and Bubba rams through the prison wall. You and Mark escape on Bubba's truck, but Bubba reveals himself to actually be Bob and a Federal Marshall. He holds you and Mark at gunpoint, with you, Mark, and Bob constantly switching weapons and where you're aiming. You can either shoot Bob or open the box.
