[Holly Christmas]

The most damming thing in the whole episode came out of Dexters own mouth when he repeated and thus reinforced what he had originally said to Callum with his don't **** with me rant..

Vile little cretin.

There's also obviously more stuff that he's said to Callum as well that Sam was going about that we haven't seem, Sam kept saying... You know how you've upset him, Dexter tried to talk over him to shut him down but Sam repeated it.
