The Last Summer (2019) Timeline Explained – Every Event in Order

Griffin is caught in an impossible position because his father is cheating with Phoebe's single mother. Telling Phoebe would betray his own family, but saying nothing betrays hers. He waits until his own mother discovers the affair and ends it on her own, which is when the secret finally comes out.

Foreshadowing: Phoebe mentions during their early conversations that she and her mother are very close, which is why the affair cuts so deep once it's revealed.

Phoebe feels betrayed because Griffin knew her mother was being cheated on and chose silence, leaving her in the dark about something that directly affected her family. The Last Summer frames this as a breach of trust that hits harder than the affair itself, because Griffin was supposed to be on her side.

Foreshadowing: Phoebe earlier tells Griffin that her relationship with her single mother is the most important thing in her life, which is why the deception feels unforgivable.

Foreshadowing: Phoebe tells Griffin early on that she needs to win the festival to pay for NYU, foreshadowing how the premiere becomes the bridge back to her.
