Episode: S03E06

A creepy telepathic alien thinks he can scare Hoshi into staying with him for the rest of her life.

The episode opens with T'Pol telling Archer that she believes there may be more than one giant sphere in the Delphic Expanse that's causing the spatial anomalies. The gravimetric energy that they radiate shoot out in rays and intersect each other; these intersections cause the areas of high concentrations of anomalies. By tracking these areas, T'Pol guesses that there should be at least fifty different spheres all throughout the Expanse. And the nearest one is not far off. TIME TO EXPLORE.

Meanwhile, Hoshi is suffering from what she believes to be hallucinations, but what we, as sci-fi viewers, know to be something entirely different. There are whispers in her quarters the source of which she tries intently to find, but fails. While she's getting ready for bed in the darkness of the artificial night, she looks around without thinking to turn the lights on and suddenly a body appears. These are projections from the alien that wants help from her.
Nothing could go wrong with this plan.
Well, far be it for Hoshi to jump to the conclusion that these are telepathic projections, so the first thing she does is get checked out by Phlox. And nothing turns out to be wrong. So eventually this alien makes contact with Hoshi for a long enough period of time to actually have a conversation, not that it helps the creep factor. He says that he can help out with their mission to find information on the Xindi. It's a sketchy lead, but any lead is a good one when it comes to the destruction of Earth, so they veer off course on their way to he second sphere to see Tarquin, the magical telepathic alien.

Up to this point, Tarquin has been projecting himself as a normal human-like alien. When they get to the planet they find that he's... a little different.
Well, this dude is definitely telepathic, so they trust him as much as that can get them. He says he can read the imprints that people leave on devices that they own, so they give him a weapon that one of the Xindi were carrying. He agrees to help, but under one condition: He wants Hoshi to stay. The frakkin creeper.

Meanwhile, the Enterprise heads on over to the second Death Star to check it out. In order to get some good readings, they line one of the shuttles with Trellium-D to guard against the gravimetric spatial anomalies. Consequently, T'Pol is instructed to stay away from the shuttle bay for a while, 'cause, ya know, Trellium-D makes Vulcans crazy. When they get closer to the Death Star it sends out a spatial anomaly that rips a hole in the hull. No big deal, though.
They eventually get all the readings and such that they need and head right on back to Creeper Tarquin. By this time, Hoshi has learned that Tarquin has had several different companions throughout his 900-year life and she is expected to be the next one. He was exiled on this planet because his race was afraid of his telepathy. So he's been on this rock without a friend save who he can lure there. Hoshi refuses to stay, obviously  because this guy is a creeper, so then he attempts to use his telepathy to trick her into thinking that Archer wants her to stay. Aaaaaand it doesn't work. He even shuts down all of Enterprise's systems for a while. The real Archer is pretty pissed about that, so once Tarquin finally lets the Enterprise and Hoshi go (begrudgingly), he leaves without intention of returning.

A while out, though, Tarquin returns to Hoshi's brain and gives them the location of a Xindi base. And that's the end.

Overall Thoughts
Really!?! He's been exiled on this planet for 900 years and never once thought of actually leaving it??? I don't see any of the other of his race around to stop him! As a whole, this episode is boring and creepy, but the Delphic Expanse Spheres are amazing and that part of the episode makes drudging through the rest bearable.
