Shadows was a superb episode of Warehouse 13 and I really enjoyed watching this episode because it had a lot of character development for Pete and his Reagent mother, Jane, who was played by one of my favorite actresses. I enjoyed the back story and it was a great way for Pete to have the truth explained to him as best as it could be. It was interesting how far back every thing went, including Ms. Frederick who looked the same in each time. Myka and Claudia had an interesting story line as well, and it was not as predictable or apparent at first what was really happening. I was very entertained and I look forward to watching the next episode of Warehouse 13!!!!!!!
