How strange to kick off the "previously on Fringe" scenes tonight with clips from a mid-Season 1 episode that was largely a monster-of-the-week! You know, "The Transformation," where Mayor Carcetti's chief of staff turns into a snarling porcupine man. But it felt nice, almost nostalgic, didn't it? Like looking at the yearbook from your freshman year?

Stranger still, that when the episode actually starts, and we see the exact same scenes we saw back then: the same blissfully happy people in first class on Vertus Air, the same announcement about strong winds and turbulence, the same old lady sitting next to the soon-to-be Porcupine Man. I suppose it would have been impractical to round up all the extras from this scene for continuity's sake. Besides, this old woman could be dead by this point.

Not Yet Porcupine Man is, as before, scribbling away in some sort of journal when his nose starts dripping dark crimson blood on the page. His seatmate again offers the same useless advice -- "put keys on your back" -- that she did originally. I remember being annoyed when she revealed that it's all bull, that she tried it herself and it didn't work. Well, thanks for sharing!

Same nervous trip to the lavatory, same shaky test of a tongue swab that turns a solution bright red, some agitated discussion with the flight attendants as Potential Porcupine tells them to round up all the sedatives and tranquilizers they can, dismissing their assumptions that this is some kind of panic attack. We don't see any discussion of weapons on board, like we did before; instead, we skip right to Buddy saying he's going back to the bathroom, and giving the flight attendant the same stark warning he did before: "When you get the drugs, you come back, you knock. If I don't answer or if I do and what you see isn't me anymore, you keep that door closed," he says.

Back to the lavatory, where he starts convulsing. He checks his eyes -- which change color to an inhuman yellow. Out in the cabin, the other passengers seem a little concerned about the agonizing grunting coming from the bathroom.

Unlike last time, the bathroom gets a visit from the air marshal, who knocks on the door, ordering the man to come out.

Which he does, looking fine. Normal eyes. Teeth still in place. Nose no longer bloody, and, most important, not an unholy beast more porcupine than man running rampage through the cabin. Marshall? Meet the air marshal. Marshal? Marshall.
