If you're looking for spoilers on the new season of Dexter, don't expect the tight-lipped cast to talk. You can however, check out our spoiler page and a ton of episodic pics after the jump, which give some clues on one major new story line this season. David Zayas, who we spoke with last week, while part of the tight-lipped cast I just referred to, also dropped a few hints on what to expect this season. Above all, the one thing we do know about season four is that John Lithgow will be tearing sh*t up as the Trinity Killer and that's reason alone to tune in this season, which draws first blood on September 27th.
