Oh, this is just cruel. Poor Scott (Tyler Posey) turns his back for one second and Isaac (Daniel Sharman) jumps in bed with his ex Allison (Crystal Reed). In a new sneak peek for Teen Wolf Season 3B (which returns January 6, 2014), the new couple is in bed together, making out and talking about Scott. Allison wants to make sure the werewolf gave his OK to the steamy session. Only things aren't exactly what they seem. Check out the video!
