In another fine turn of the pen by Thania St. John, this week's episode of "Eureka" on Syfy was a frothy concoction of fun sprinkled with poignancy.

Posing the mystery of how can a person drown in an airtight car, a restaurant bathroom or an empty whirlpool spa was intriguing. It felt a little like Alice falling down the rabbit hole, but eventually, the solution was revealed to be, not a murderous corporate-drone worried about job security and the scarcity of government funding or even the miraculous super-absorbent diapers, but rather irradiated syn-water (synthetic water).

The only evil going on was the failure to properly shield the water during the radiation testing being conducted on Kim 2.0 in order to extract her data.

In the midst of the syn-water sleuthing, we were introduced to the latest Eureka transplant, Dr. Bruce Manlius (aka: Dr. Manly). Just watching him do a double-take over Tess the Mess' transformation from ugly-duckling to swan was fun to behold. Then watching Tess nearly buckling at the knees whenever he was around was spine-tinglingly adorable as well. It is telling that those two had way more sparks than Tess and Carter.

While Tess and Dr. Manlius were so obviously distracted by each other, in contrast, we also witnessed the tragic decline of Kim 2.0 -- and Henry's realization that he was going to lose Kim all over again. Tess, unfortunately, said it best when she sadly observed, "that sucks ... finding the person that makes you happy, but not getting the happily ever after."

This was an episode with plenty of laughs and hardcore science, but it was also heartbreaking. Henry's quiet acknowledgment to Kim 2.0, "You're not Kim. I know that. But you do have her laugh, and her mind and her spirit" and Kim 2.0s resigned acceptance, "I'm just a copy and you have to let me go," broke our hearts.

It is starting to feel like Henry is doomed to have Kim die tragically on him time and time again. Maybe when he messed with the original timeline, this was his punishment. To watch Kim die over and over again. If that is true, then that is one nasty curse. Will he and Carter have to eventually travel back to the future to fix it?

What Worked

Everything having to do with Jack and Allison. For Jack's comment at the beginning, "I'm a birthing coach, I take my responsibility seriously," was a fun foreshadowing of Jack's "sympathy pregnancy." Whether it was watching Jack waddle down the stairs or complain about his aching back, it really made you believe that he was going through a sympathetic pregnancy.

It was almost a shame when they revealed that it was brought on, not by his close connection to Allison, but because the souped-up baby monitor had inadvertently connected he and Allison, instead of Allison and the baby. Jack had really wanted to go through the pregnancy experience with Allison and he looked so crushed when it was taken away from him.

With Zoe nearly all grown up, it is easy to forget what an adorable father he would be to a baby. But seeing his pain over that loss of the connection was touching.

What Didn't Work

While I was ecstatic to finally see Carter using a Bluetooth to talk on his cellphone while driving in his jeep, it was like popping a balloon when I saw Jo using her hands to talk on her cellphone while sitting in her car. While technically it is not illegal to sit in a parked car talking on a cell phone, it did nothing to help educate that one should not be driving and talking on a cellphone while holding it up to your ear. Plus, this is Eureka folks -- hands-free technology and devices should be a "given."

This week was also another Jo and Zane-light episode and that was a shame because Jo's caustic wit would have been fun in figuring out the drowning mystery. Plus, with a razor-sharp mind like Zane's around, you would have thought he would have been right there to help with downloading Kim 2.0's data. Their absence in the midst of these big events felt glaring.

Lastly, the scenes with Allison and Jack feel much more warmth-infused and loving than any of the scenes with Jack and Tess. I say enough already with forcing an unnatural relationship upon the viewers. Surely nobody is buying that Tess is a serious love interest for Jack -- especially now that they have introduced "Dr. Manly." Let us bring back the focus of the story and not make us cringe over couples that clearly do not belong together.
