- A script is being written that will very much be a peek into Joan’s family, in particular her father! “I don’t think we’ve ever said any of this explicitly in the show, but the way we’ve always imagined it is Joan’s birth father fell out of the picture and her mother remarried with the last name Watson. So this story is based on that understanding of her circumstances,” says executive producer Rob Doherty. ”We’re just going to find out a little more about what went down when she was a kid and a little more about the status of her birth dad.” But, he adds, this isn’t an episode that will see the introduction of her father, saying, ”We may meet somebody down the line, but this episode is another little window into who Joan is and where she comes from.”
- Lucy Liu is set to direct an upcoming episode.
- We will eventually see a return from Broadway star Steve Kazee, who appeared a few episodes ago as a man who showed interest in Joan. “We haven’t quite crafted a return for him yet but we have a way of figuring these things out,” Rob Doherty says.
- Sherlock's brother Mycroft will be back and forth over the course of the season.
- Is there a chance that Natalie Dormer could return to Elementary? Yes, but don't expect Irene Adler to pop up in the first half of the new season, which picks up months after the events of the finale. "Is Sherlock completely over everything that happened? No, but he tends to internalize and compartmentalize everything," executive producer Rob Doherty says, noting that when she does return, it won't be as a villain -- or at least not the villain of Season 2.
- The format for season two will be in a similar vein to that of the first, which became more serialized as it went on. "We will absolutely have standalone stories and cases, but there will be certain stories that you can arc over a run of shows."
- No plans yet, but Robert Doherty would love to bring back Roger Rees as Alistair with the right story.
