Timeless is going back in time to the Depression.
On Sunday's episode, titled "The King of the Delta Blues," Connor Mason -- the creator of the time machine the team uses to transport to various eras -- joins in on the time-traveling fun for the first time with the Timeless heroes. Their new mission: Travel back to the Depression-era South to rescue the life and legacy of Robert Johnson, godfather of rock 'n' roll.
In ET's exclusive sneak peek, Flynn (Goran Visnjic) observes that things "must be awkward" for Lucy (Abigail Spencer) at the moment, with Wyatt's wife, Jessica, back in the picture. When Lucy assures Flynn that he's mistaken, he aims to get to the root of her sadness, while at the same time pushing her buttons.
"Wyatt and Rufus giggling like schoolboys about Wyatt's late-night activities with Jessica, that wasn't awkward?" Flynn asks, to which Lucy responds with an emphatic "no." And a mention of the bottle of vodka she's been secretly stashing under her bed as her temporary cure for her current situation doesn't exactly leave Lucy with a smile on her face.
Flynn then brings up the journal Lucy gave to him. "At first, all I cared about was it was a tool to take down Rittenhouse, but the more I read it, the longer I stayed with it, the more I felt like I knew you, understood you," he explains, attempting to connect with her. "Sometimes, I feel like I know you more than you know yourself."
"What do you want from me, Flynn?" Lucy bites back. "You don't know me."
"Well, I guess we're having our own awkward moment right now," Flynn accurately states.
Though the timing of their conversation isn't ideal -- what with Lucy in denial over what could have been with her and Wyatt romantically -- could there be something brewing between Lucy and Flynn? Watch the exclusive sneak peek above to find out.
Timeless airs Sundays at 10 p.m. ET/PT on NBC.
