Tim and Lucy share their first real on-screen kiss in The Rookie Season 4 finale, and then have their big, “for real” romantic kiss in Season 5 Episode 1 when they go undercover as a couple.

When do Tim and Lucy kiss?

  • Their first kiss happens at the end of Season 4, after years of buildup and “will-they-won’t-they” tension.
  • In Season 5 Episode 1 (“Double Down”), they kiss again while undercover as a couple, which is widely treated by fans as their first properly romantic, in-the-open Chenford moment.
  • It takes about four full seasons and roughly 70+ episodes before they finally kiss, which is why fans talk about how long the slow burn lasted.

Many fans call the undercover kiss in the Season 5 premiere “the first real kiss,” because it forces both Tim and Lucy to confront that their feelings are more than just partners or friends.
