(Season 4, Episode 7) Sometimes you have to fight for what you want. Sometimes it's too late. And when you're dealing with time travel, that can take on a whole new meaning. Zoey returned to Eureka this week for a visit, where we discovered that she's moved on to a new Mr. Right.

But, as this is Eureka, a visit to town just wouldn't be complete without falling hands first into the newest scientific danger. It was a fun one this week, though lighter on the action than we've seen in recent weeks. Perhaps Colin Ferguson was too tired from filming 'Lake Placid 3' to handle it, so instead we got a fairly low-key, though no less deadly, conundrum for him to try and solve with his down-home charm and smile.

Plus, did you really think you could pluck a man from 1947 and drop him into the Information Age, at a high-tech company like Global Dynamics no less, and no one would notice?

It looks like Dr. Grant's secret is out, though what it means remains to be seen. The woman at the end who's the daughter of one of his contemporaries looked cryptic enough, but I'm not sure what she could have meant by them waiting for him. Maybe they want to worship him! Regardless, she knew that Dr. Charles Grant was in fact the same Dr. Trevor Grant who vanished in 1947 on the site that would one day become Eureka. It's actually pretty exciting to think they're going to start exploring his unique situation a little more. And it's about time, so to speak.

As fun as he's been in the role of dashing man with quaint and archaic charm, it's about time the brilliant James Callis gets something a little meatier to sink his teeth into. What should be even more delicious for fans is when he inevitably has to call on the Sheriff for help.

Trouble for our time-tossed gang may have started when they asked Zane to help them hack the Department of Defense systems to try and fix the problem of who was looking into Dr. Grant's fabricated file. Zane's a little too smart at doing illegal things like that, and he picked up on the fact that Dr. Grant isn't exactly who it says he is. Jo probably should have agreed to look into it, if only in the hopes of getting him off her back, but she's emotionally distracted, so we'll let it slide.

This week, the Sheriff was beside his daughter in consternation and grief. At one point it was because she was petrifying from the outside in, but I think the more dramatic development was the reveal that the new man in her life is none other than Zane Donovan. The Zane Donovan who proposed to Jo in the original timeline and has more recently been warming up to her. Poor Jo walked in on the two of them canoodling over her recovery.

First, the episode starts with a delay on construction of her house because of a supposed archaeological find and then she has to have her heartache smeared all over Allison's lab table. I hope the writers come up with something more positive to do with her character this this season than just make her suffer endlessly. She's too good of a character to waste this way. Plus, she's a much better fit for Zane than Zoey.

That said, I enjoyed this more grown-up version of Zoey, talking all scientific and over her dad's head. I think that may have been one of those rare moments when Jack was able to see her as an independent woman instead of the little girl he needs to be incredibly overprotective of. I'm not sure if Jordan Hinson is going to be available to return to the series (certainly 'Hank' tanked miserably), but I think it would be nice to explore the two of them developing this new and more mature relationship. It would certainly be good for Jack's development.

Henry took another big step in his courtship of his "wife," by finding a way to woo her in a different way from his own instincts ... apparently, he and her Henry think a lot alike. His rendition of "She Blinded Me With Science" was a lot of fun, though Fargo as DJ had to permanently eliminate any intimidation he had over the staff at GD. After seeing him dance around like a goober, how can they see him as anything other than a goofball?

As much fun as the weekly disasters usually are, I found this week's petrification storyline a little dull. Thankfully, the ongoing threads had some nice beats to them to keep things moving, and some seeds were planted that can grown throughout the rest of the season into flowers of big-time drama and conflict. I've always thought 'Eureka' handled the big things better than these diversions anyway.

The biggest thing Jack did this week was finally, after 50 episodes, kiss Allison. At this rate, the two of them will shack up in Episode 100. It's about time he took that bold step, because now we can have even more tension when Dr. Grant finds out. And was it just me, or did anyone else expect Nathan Stark to pop up at, or right after, that climactic moment. I don't know why, but it just felt like the kind of twist the writers would love to throw our way. Who's to say they still won't.
