I like it when shows change things up and defy expectation. For instance, the writers introduced H.G. Wells as the next great villain of the series, and so it was assumed that this was the direction the story would take. This episode presents a different side of the issue, and presents the possibility that Wells is not quite the villain she appears to be.
Or, perhaps more accurately, she may have an endgame that will run counter to the desires of the Regents and the best interests of the familiar Warehouse 13 gang, but that makes perfect sense from her perspective. And that would be a great direction to take with this plot thread. It would certainly help to make up for the lack of follow-through on Wells and her activities over the first half of the season.
I thought Myka, Claudia, and Wells made a great female empowerment team, especially considering the crisis at hand. Three lovely women coming to the aid of a bunch of supposedly tough male wrestlers? Good stuff all around! Even Pete and Artie were, in their own ways, making choices to gain the favor of women with strong personalities.
I like the callback to the vet in "Beyond Our Control", and I hope we see more of her and Pete in future episodes. I also want to see more of Dr. Calder, because it opens up a side of Artie that hasn't really been seen too often. I like how his father-figure role has evolved this season, and a potential romance would only continue to broaden the character.
For the most part, I'm just happy with the direction that the season has taken. I think the first few episodes were a bit rough, as they made the necessary adjustments to expand the storytelling opportunities, but they're hitting their stride now. It's not on the level of "Eureka" this season, but it's a solid part of my DVR list.
