Supernatural kicked off its 10th season tonight and the premiere episode got series star Jensen Ackles out of his shirt, as his character Dean got a romp in the sack. Unfortunately, it was only one scene of the episode. Misha Collins also showed a bit of skin in the episode, as his character is also shown in bed. Due to his robe, there isn’t much shown in the two scenes before he gets fully dressed.
