Warehouse 13: Implosion
What I have been saying about Warehouse 13 since almost the first episode is that they need an enemy, someone else who knows about the artifacts and is collecting them. It, after all, seems impossible that there wouldn’t be someone else who know about these things.
This week they had a new villain that seems likely to show up somewhat regularly. A former warehouse agent who makes things much more difficult for them. After all, a sword that turns a person invisible is only dangerous if there is someone dangerous using the sword.
The other major thing is giving us an idea that there is more in Arti’s history than the warehouse. And beginning to put a little more question of if we can trust him. This makes sense because he is an odd fellow and you can believe that he might just be dangerous.
The Implosion bombs were also quite interesting too. I’m not certain that they would be better than an explosion bomb, since most of the damage bombs do is shrapnel. But that isn’t all that important as it’s a minor part of the story.
Overall I have been enjoying Warehouse 13 and they are still adding complexity and interest to the show making me want to watch it more every week.

Good point about needing a big villain.
