Continuity mistake: In Season 6, Episode 10, Dexter and Harry are in the motel room where Travis was staying (timestamp 1). Dexter decides to post on Gellar's blog (impersonating Gellar), and the screen on the computer shows the post date as Sunday, November 24, preceded by a Sunday, November 20 post. Aren't Sundays supposed to be a week apart? Then in episode 12 (timestamp 2), Travis is in Dexter's apartment and sees the poster for the Noah's Ark school play. The date posted for the play is Saturday, October 8, ie. in the past compared to the earlier episode. Plus If November 24 were on a Sunday, then October 8 should have been on a Tuesday.
