[Warning: The below contains MAJOR spoilers for The Summer I Turned Pretty Season 3, Episode 2, “Last Christmas.”]

The Summer I Turned Pretty Season 3 is keeping the love alive for Jenny Han‘s other popular To All the Boys I’ve Loved Before franchise with a special planted easter egg that could also hint at Belly Conklin’s (Lola Tung) endgame.

Before fans ever debated which Fisher brother was best for Belly — Conrad (Christopher Briney) or Jeremiah (Gavin Casalegno) — Han won them over with the romance of Lara Jean Covey (Lana Condor) and Peter Kavinsky (Noah Centineo) in the film trilogy, the second entry of which is based on her book P.S. I Still Love You.

The book gets a shoutout in a crossword puzzle moment during The Summer I Turned Pretty‘s Season 3 “Last Christmas” episode. But does the sweet nod have a deeper meaning?
