Appearance: "Olivia"
Explanation: After Sally Clark sacrifices herself in a covert assault on the alternate-universe by bursting into flames, the extensive burns apparently didn't cause much trouble for Fringe officer Lincoln Lee, who was back on his feet two episodes later with some handy regenerative nanite treatments, his burn-face steadily improving provided he doesnt' stray from the hyperbaric chamber for too long.
Infringe-ing on Possible?: Only Over There could walk around looking like Freddy Krueger without phasing anybody, and what's with the treatments only having a temporary effect?
