User blog comment:Le Rusecue/Timeline of Dexter?/@comment-1405841-20111006002349

The way I look at the first episode of Season 5 is that they pretty much filmed it (or they got a VERY similar baby) around the time the finale for the fourth season was finished. I might be wrong, but it just feels so close to the look of everything by the final episode of season 4...not a whole lot of aging going on and what not.

Harrison is 1 years old by the end of Season 5, then an entire year passes and it's 2011 in Season 6. In the first episode of this new season, he goes to his 20th high school reunion of the 91' class. Now note that it's time for Dexter to enroll Harrison in school, if there is an urgency to do this that means right now we're looking at about July or August monthwise in the Dexter storyline. But back to years...

The timeline is a little off, because apparently Dexter years are the same as our years...if it's 2008 here, it would be 2008 there. The thing is, going back to Season 5, he is said to be 6 months old in the second episode of that season. Six months and he ages six more months to the end of the season. That means there is a time gap between just about every episode that doesn't end like a serial (meaning events play right into the next one, pretty much like the end of each season the last few episodes are closely tied timewise to each other). And now flying back to Season 3, Rita's pregnant...she's not showing by the wedding but the baby's born and 3 months old by the start of Season 4. That means Season 4 is stuck in a very weird, weird timescale to the rest of the seasons...because Harrison doesn't age all that much through the whole thing yet there are these huge timegaps here and there.

Ugh, as far as timeline goes...we're all supposed to assume each season takes place within the appropriate year and leave it at that .__.;
