Set on Christmas Eve and Christmas Day, the Timeless finale will pick up after that Season 2 cliffhanger, following Wyatt (Matt Lanter) and Lucy (Abigail Spencer) as they hop across a few centuries and continents to undo Rufus' (Malcolm Barrett) death. Goran Višnjić, Paterson Joseph, Sakina Jaffrey and Claudia Doumit are also reprising their roles in the two-hour event.
The finale is expected to tie together some of the show's loose ends — including the big reason why future Lucy and Wyatt are willing to break all the rules to face their past selves — and hopefully bring a satisfying conclusion to those characters who became so important to fans that they flew a helicopter over Comic-Con to save them.
For those Timeless fans who want to ~live in the moment~ here's what you need to know.
