This episode managed to take two very different concepts and mesh them together into a neat little package. And I'm not talking about Myka's patent leather getup, either!
The main plot was the kind of love letter to comic book geeks that usually goes horribly wrong. This time, it was handled fairly well. The premise of "Warehouse 13" is actually perfect for the purpose of inserting some comic book logic into the equation. This is, after all, a series about paranormal artifacts causing unusual and unexpected consequences. How many comic book heroes are essentially given that very origin?
It was great seeing Jewel Staite and Sean Maher again, even if it was mostly bittersweet. Who wasn't wishing that it could have been a resurrection of "Firefly", somehow? The guest roles were fairly thin, but Jewel was gorgeous as ever, and it was great to see Sean again. Much as with the season premiere, the majority of the cast was fine. Pete was still a bit too flippant for my taste, though I wasn't quite as averse to it during this episode.
The second plot thread, dealing with the aftermath of the premiere in the warehouse, was also very well done. It was good to see everyone working out their emotional and psychological baggage. I have some hope that the whole Artie/McPherson interaction will continue in some small fashion. (As an aside: just what kind of partners were they?)
But I've actually found a character that annoys me more than Pete: Leena. Genelle Williams just doesn't seem very convincing in that role. Compare her to Allison Scagliotti, who is very natural in her portrayal of Claudia, when they share the screen. Williams' line delivery always feels forced in comparison.
