Michael C Hall and John Lithgow sat down recently to discuss the shocking season four finale of Dexter. Throughout the season Lithgow played a serial killer, “The Trinity Killer”, who killed Dexter’s wife Rita before Dexter had a chance to kill him in the last episode.

About the death of Rita, Michael C Hall said, “I did think it was a really bold stroke in terms of resetting the stage in terms of what’s to come, whatever that may be. I think more than anything I was horrified and I felt for the audience, it’s the sort of thing that ties people in knots.”

Lithgow commented that it was the contradiction of his character that made him interesting. “My most appalling scene was the very first, shortly thereafter you see me walking a dog on the sidewalk at night and its like NO! creepy. Trinity is a completely two faced man, he appears to be so nice and so kind and yet by the same extreme he is completely despicable I think tension is what is so scary about him.”
