Spoiler Alert: Inside the Final Fosse/Verdon, With a Surprise Cameo and All That Jazz

The final edition of FX's limited series Fosse/Verdon aired tonight on FX, and it found some periods of reflection in the lives of protagonists Bob Fosse (Sam Rockwell) and Gwen Verdon (Michelle Williams).

Titled "Providence," — both as a reference to religious spirituality and the middle name of their daughter Nicole (Juliet Brett) — episode 8 finds Bob and Gwen at a crossroads. To quote a song from Sweet Charity, Gwen is wondering where she's headed as a performer, while Bob, coming off his 1978 Tony-winning Dancin', chooses to look back and put his life on the big screen, in the form of All That Jazz. The episode takes us through the death of Bob's best pal, Paddy Chayefsky (Norbert Leo Butz), who succumbs to cancer at the age of 58 in 1981, and through to Fosse's own final moments in 1987, foreshadowed at the beginning of the series.

There's also a surprise cameo midway through the episode — and if you haven't watched it, this is a MAJOR SPOILER ALERT. In fact, here's a gallery of images to peruse as you decide if you want the surprise cameo ruined if you haven't watched:

If you've read this far, you've probably already seen it. Lin-Manuel Miranda, one of the series's executive producers, makes an appearance in a sparkly black dress shirt to play Roy Scheider in the sequence of filming All That Jazz. Kudos to prolific tweeter Miranda for keeping it under wraps for so long. Even we were surprised.
