I found this on j-padalecki.org, and there are some pictures of Jared on set, filming what is believed to be episode 6 of the season. Some of the pictures are a bit spoilery, but others are not. Here is the link if you want to check them out, and I do have to say that Jared is looking sexy as ever.
