Since then, all three actors have moved on: Julia Stiles is now married to Preston Cook, with whom shares a son, Strummer Newcomb (via People), while Michael C. Hall wed Morgan MacGregor in February 2016 (via People), and Jennifer Carpenter has a son named Isaac with her husband, musician Seth Avett (via People).
There also doesn't seem to be any hard feelings between Hall and Carpenter. The two continued to work together on "Dexter" after their split, and both are slated to reunite for the show's upcoming revival, although Carpenter's character was killed off in the series finale. "Our marriage didn't look like anyone else's, and our divorce didn't either ... I said it before, just because the marriage ended doesn't mean the love did," Carpenter said through tears at a "Dexter" event back in 2013 (via Us Weekly). Hall agreed, explaining that "Jennifer and I worked through whatever was going on with us personally the way we did and maintained telling the story was never in question. It was always what we needed or wanted to do." It seems like there are no hard feelings in this rumored love triangle.
