The father flashbacks with the tie-knotting lesson -- very simple and yet moving. If we thought that we weren't going to be seeing lots of James Remar in the past season, we were wrong. Dexter's frequent conversations with his late Dad were psychological delights, and if we read our signs correctly, Debra will now be finding out secrets about her father in next season.
I loved LaGuerta making the cupcake ritual that she shared with her murdered attorney friend Ellen Wolfe her own, and sharing the ganache-frosted treats with her new detective Debra. LaGuerta symbolically and literally closed the file on her ex-lover Miguel Prado and his poisonous deeds, and has moved on. A nice female bonding moment for both LaGuerta and Debra, who have been at odds in the past, but only because they both are tough-minded cops with similar ambition. I loved Debra making the joke -- how being in a dress made her feel like a transvestite -- to Dexter when she visited him in as he finished dressing for the wedding. Avoiding the usual sentimental drivel, she was as sharp-witted as always and also shared Dad's tie-knotting ritual with Dexter, and the affection between these two is a terrific portrayal of the sibling bond.
I also was amused by the many romantic hook-ups this season, with even Masuka finding a girlfriend in the savvy adult entertainment consultant Tammy. The humanization of Masuka from a strictly-creepy lech into someone more conventionally likable hasn't made him lose any of his edge, and you don't have to feel that he is so clueless anymore. That's good. Angel seems to have found a worthy love match in the tough but devoted Lt. Barbara Gianna. Now that Debra has embraced the laidback and appealing Anton, her love life is in good shape, too.
Probably the least interesting match of all is Dexter and Rita, but the existence of a first mystery marriage for her might bring interesting repercussions in the future. I'm not sure how much Dexter will play with the conventional new baby plotline -- how much can you do with that? -- and here's hoping that the next season is as surprising and ultimately as satisfying as this one was...or even more so, perhaps.
