Being a new viewer as of the second season, I didn't know anything about Artie's past, so I enjoyed this episode for that reason alone. It reveals quite a bit about his strength of character and continues to render him as more than just the source of quick and dirty exposition. It's also good to see him working with Pete and Myka, since much of his time this season has been spent with Claudia.
But the real bonus in this episode was the return of H.G. Wells. I love what they did with the character, and how it has tossed some complications into a team dynamic that has already done so much to avoid stagnation. The character was very sympathetic in this episode, and it provided a nice counterpoint for Artie.
The real question, though, is whether or not Artie is right. If H.G. Wells was being honest, then Artie is being stubborn, acting out of a distinct lack of information. But there's still a great deal of potential for H.G. to be manipulating the situation, and perhaps all the light shed on the Regents and the hierarchy behind the Warehouse system is meant to lay the groundwork for some sort of conspiracy. After all, who doesn't expect H.G. to be working on a time machine again, in some attempt to save her daughter's life?
But that seems just a bit too predictable, and I would rather they take the unexpected route. Why not have H.G. be completely sincere? Granted, it's unlikely that they would keep her around forever, since they don't really need to expand or alter the cast right now. But why make her a stereotypical villain? Of course, they still need to explain why McPherson would have gone through all that trouble to release her, and why she took the actions shown in the season premiere.
If there was one weakness in the episode, I thought it was Claudia's subplot with Todd. What was the point of having Todd come back, only to be shuffled off again? I also thought that Claudia's emotions were a bit over the top, especially towards the end. Considering that Claudia has been the breakout character for me on this show, I'm concerned. Others have noted that her character has been a little too overexposed this season, and it would be a shame to kill all that accumulated goodwill.
