Dean Norris aka Big Jim has gotten so used to being trapped Under the Dome, that now he travels with his own personal dome to be under.
To find out why he likes it so much tune into CBS at 10p to see who he kills next in his own sadistic way.
BTW you Time Warner subscribers will be happy to know that CBS and the cable company have finally reached an agreement and the Eye should be back on your TVs as you read this.
