After four seasons of a slow build up and sexual tension, in the Season 4 finale, “Day in the Hole,” Tim and Lucy have to go undercover as a couple. The colleagues get together after hours at Lucy’s apartment to work on their pretend-PDA. Tim gives her a quick peck that leaves Lucy wanting more.

“Sorry, is that it?” she says.

Tim, taken aback, stammers, “You know what, if you’re going to criticize, then–”

But then Lucy takes command of the situation, pulling Tim into a steamy kiss that lasts a full seven seconds… and is only broken off when Lucy’s roommate barges into the room.

Fans naturally were very excited, singing Lizzo's "About Damn Time" at the top of their lungs. The Daily Express logged some Rookie fans’ reactions to that big moment for Tim and Lucy. “I can’t believe the long-awaited Chenford kiss finally happened,” one person tweeted. “It was worth waiting four years for this scene.”
