    Of Data and Dark Matter Nebulae.

    Michelle Scarabelli takes off the AlieNation "Newcomer" spots and appears as "Jenna", an eccentric crew-woman who becomes attached to Data like a tether.

    It's very interesting to watch Data's process: of course he has to get everybody else's opinion before he acts. He gets great advice from Guinan and Riker.

    When watching Data interact with the O'Briens in 10 forward, we see that even though he cannot participate in humor internally, he is finally able to understand how to make a joke and make it funny, even though he himself doesn't understand the joke or can actually laugh at it. That's what makes him the most humorous member of the crew, because what for for him is an innocent question can come off with hilarious results because of the way he asks it.

    But this situation is a little bit more complicated than merely figuring out what humor is, this is in fact Data's first girlfriend, not counting his interaction with Tasha in season one.

    In the meantime the ship is exploring a very interesting looking dark matter nebula. This provides the backdrop for Data's exploration of sex and relationships.

    The two subjects counterbalance themselves in this episode. While Data's meanderings give us the humor, there is actual danger for the Enterprise that is not initially seen. Some bad things have to happen before they actually understand the level of danger they are in.

    The two issues are resolved, not too well for Mr. Data. In theory, my theory: Data should not have created a subprogram to govern his relationship, he actually was doing fine without it. This is just another example of how Data's interpersonal experimentations fail with hilarious results, hilarious for us, Data of course has no feelings.

    This is what he always says, but after Jenna leaves him, and he deletes the program, we are left with an image of Data picking up his cat Spot and holding it. That image says a lot. That although Data does not have feelings in the way humans have feelings, he does have some Positronic version of affection. He loves his cat, we know he loves his cat. I suppose Data has become "used to Spot's sensory input information".

    Patrick Stewart "captained" this particular episode as well as Picard captains the Enterprise.

    A great romantic episode!

    Data is the best character in TNG , and he prove it once again in " In theory" , he decide to have a girlfriend, and it was hilarous , touching , intelligent Directed by Patrick Stewart.

    Season 4 continue to deliver as the best of the first 4 Seasons, now ready for the final, to see Worf seek redemption.

    Intriguing

    The main plot of this TNG episode which is the dangers the Enterprise encounters exploring a nebula takes a backseat to a romantic encounter Data has with Ensign Michelle Scarabelli.

    Scarabelli has had a breakup and she's finding Brent Spiner intriguing if not attractive. As for Data we have it on the authority of the late Tasha Yar from season 1 that Data is a fully functioning android in all respects.

    I think you'll find this episode intriguing too.

    Begging for it to be over

    A brilliant acting performance form Brent Spiner, as usual, but just a dreadful episode that was agonizing to watch. One of the only episodes where I just wanted it to be over. The main plot was forgettable, and the side story was unforgettable, but not in a good way. As Riker would say, sometimes you get the bear, and sometimes the bear gets you. The bear got this one.

    Data, in Love....Sort of

    This offering is really ludicrous. While Commander Data is a fascinating creation, for someone to want a romantic involvement has got to push the envelope. A young ensign, on the rebound from a relationship with a jerk, finds Data's byplay amusing and fun. She actually kisses him on the lips. He processes this and decides it would make an interesting investigation of human dating ritual. Of course, he now feels he needs to look into historical depictions of the process of couples getting along. In a priceless scene, he shows up at her quarters, announcing, "Honey, I'm home." He then dotes on her for a while and then creates a confrontation where he treats her badly. In his search, he has found that often relationships thrive after a fight. This episode also involves a kind of entity that is aboard the ship and part of an area of space where the Enterprise is vulnerable. Data continues to do what he does, ignoring his new experiences, and helping to save the Enterprise. A very odd episode.

      This is the first episode to be directed by Patrick Stewart, the second cast member after Jonathan Frakes to direct an episode.
    • Goofs
      Referring to the mess in Jenna's quarters, Data describes her to apparently "have an *adversion* to orderliness". He obviously meant to say "aversion".

      Captain Jean-Luc Picard: Yes, I've heard, Data. And I would be delighted to offer any advice I can on understanding women. When I have some, I'll let you know.
