If you watched The Kissing Booth 2 over the weekend—stop reading this right now if you haven’t—then you know the film ends with Elle and Noah together again, despite Elle sharing a spicy and spontaneous kiss with the school’s new “snack,” Marco, during their Dance Dance Mania competition. Elle’s convinced Noah’s the one, but as Marco is advised to let her go, because she’s not worth it at the end of the film, he disagrees, and with a steely gaze utters what adds up to a “we’ll see about that” in response.
