Fans of showrunner Steven Moffat’s Sherlock and Doctor Who have long been obsessed with seeing the Doctor (starting with Matt Smith’s tenure as the Time Lord) and Benedict Cumberbatch’s Sherlock Holmes cross paths on the small screen. Not the whole fandom of course, but some.

The fictional pairing called #WhoLock gave rise to a TARDIS-load of fan-made videos as well as hundreds of works of fan fiction and fan art. While Moffat and Sherlock co-creator Mark Gatiss have mostly been against a crossover between the two series from ever happening (due to several production hurdles, the first one being cast availability), we may just have the next best thing.

Director Rachel Talalay took to Twitter last night to publish a photograph of 12th Doctor Peter Capaldi sitting in Sherlock’s armchair at 221B Baker Street and the game is now afoot. Talalay, who worked on both Doctor Who and Sherlock (she helmed the first episode of Season 4, “The Six Thatchers”), wrote that Capaldi materialized visited her on the set sometime last year while he was filming a guest-starring stint on the now-canceled Doctor Who spinoff Class.

Fans of #WhoLock were of course thrilled about the photo, with some of them being mind-blown imagining the Doctor as a potential client of Sherlock or Sherlock being a client of the Doctor’s. Whatever works. Check out Talalay’s Tweet, followed by a couple of great reactions from fans:
