I just caught the tail end, but he said a few interresting things. He knows how the season ends. Jimmy asked about the creature, and whether we would find out what it was. Dominic said there were 14 pages of script that he didn't know about (because he wasn't part of it, and didn't want to know), and it could have been in there. He referred to the creature as "He", saying "He comes back...", then quickly corrected himself and said "IT comes back". Kind of interresting.
He also said that he knew there had been a lot of repeats lately, but that every episode was new from now to the end of the season. Yeah!
