“Harbinger” is episode fifteen of season three of Star Trek: Enterprise.
The ‘Previously…’ covers a lot of different episodes.
Trip is doing Vulcan neuropressure and talking about how Reed might be tough to get to know, but you realise there’s no-one else you’d rather have at your back. And he’s not doing neuropressure on T’Pol. The woman is Amanda Cole, one of the MACOs and she thinks Reed looks on them as the enemy. No; competition, maybe. She says neuropressure would be good to incorporate into MACO training, but Hayes hasn’t changed the regimen since she joined. He likes consistency. As does Reed, according to T’Pol. The two are similar. Maybe that’s why they get along so well – sarcasm. Then Cole kisses Trip.
Using the coordinates got from Degra in the previous episode, “Stratagem”, Enterprise is now heading to hopefully where the Xindi weapon is being built. Reed arrives in the captain’s ready room; Major Hayes wants to put Reed’s security team and all senior staff through training drills. Reed is not enthusiastic; the captain says the MACOs weapons and tactics are 2-3 years beyond theirs. Why not let them pass on some expertise? Reed thinks they should eb the ones doing that; their experience is practical. Captain Archer reminds him that the MACOs have gone up against a few aliens too.
Dr Phlox has called T’Pol to sickbay. Amanda Cole has been suffering a mild headache and he thinks Trip has been applying neuropressure wrong. Phlox has cautioned Cole and suggests T’Pol has a word with Trip. And perhaps T’Pol could schedule a session with Cole to undo some of Trip’s work. T’Pol does not look enthused.
Reed is speaking to Hayes about arranging training; Reed seems to be being difficult for the sake of it and Hayes thinks so too. Reed thinks Hayes should have come to him, not the captain. Hayes thought Reed would turn him down flat. Probably right, but it was his decision.
The captain enters the bridge; Travis is having problems as it seems the stars keep shifting position. T’Pol has detected an unusually strong gravimetric disturbance 3 light years away. Enterprise heads to take a look and comes across something very odd, that T’Pol says is a convergence of spatial anomalies. Hoshi has detected a signal inside the mass and T’Pol has detected a small object about 5 metres long, close to the edge, with humanoid biosigns inside. Weak biosigns. The item is grappled, then the cloud engulfs Enterprise and things start getting strange onboard. Trip has to back them away.
The pod has a humanoid inside it, linked up to a lot of wires. He’s taken to sickbay and Phlox says they’re suffering from rapid cellular degeneration. He doesn’t know if it can be stopped. The humanoid, once revived, demands to be taken back to his ship and won’t answer any questions.
The captain joins T’Pol and Travis in the command centre; Travis has new data so they can navigate the problems caused by the disturbance. Which T’Pol says is expanding at a rate of several kilometres per second and its location is equidistant between five spheres. There was a plane that was once inhabited inside. It isn’t any longer. The alien might be the last survivor. The captain wants T’Pol to take look at the pod.
The training Hayes conducts has some problems. T’Pol gets distracted by Trip and Cole enough that she gets slugged in the face. Reed calls an early end to it when Travis ends up bleeding from the mouth, arguing with Hayes after class.
T’Pol speaks to Trip about his neuropressure with Cole. He wonders if she wants to join them both. T’Pol, it seems, has been watching the two of them very closely.
In “Chosen Realm”, the Triannon believed that the builders of the spheres, the Makers, were reshaping the Expanse. Now it looks like that may be true. Trip and T’Pol end up discussing their issues, as do Reed and Hayes. Though they use very different methods.
