Something terrible is about to happen in Season 4 of Sherlock. At least, that's the unmistakable impression that comes from the first trailer for the new season, released Sunday at Comic-Con. That reading is aided by things said by titular star Benedict Cumberbatch, co-star Amanda Abbington, producer Sue Vertue, and co-creators Mark Gatiss and Steven Moffat at Sunday's Sherlock panel.
There are definitely a few mild spoilers in the trailer and quotes from the panel to be wary of if you're still pushing your way through Season 3 (that's your warning to stop reading). For one, Moriarty (Andrew Scott) doesn't look dead. "Something's coming. Maybe it's Moriarty. Maybe it's not," says Sherlock elusively in the trailer, shortly before he walks into the swimming pool where he confronted Moriarty in Season 1. Though they don't commit to anything, there's some serious teasing of him playing a central role.
There's also quite a bit of Toby Jones in the trailer, who has a seriously wonderful sinister laugh. And though he and Mycroft Holmes (Gatiss) get a good amount of screen time in the trailer, conspicuously absent is Martin Freeman's Watson, who only appears briefly and wasn't a part of the panel.
