This has been a lovely second-half-of-the-season for Warehouse 13, really one of the strongest sets of episodes the series has put up, and tonight’s season finale is just what you’d hope for and more. Joanne Kelly (Myka) and Eddie McClintock (Pete) give perhaps their best performances of the entire series, and just wait until you see… sorry, no spoilers. Just watch tonight, and prepare by checking out the TV spot and clip:
