The series began when Max saved Liz’s life, so it’s only fitting that they get their own proper send-off. Before any of the graduation chaos even started, Max proposes to Liz on her roof, the setting for so many important scenes throughout the show.
Sometime after they all had to leave Roswell, Liz sends her diary back to her dad so he can finally learn the truth about everything. She asks him to share it with Maria’s mom, too, before destroying it and burying it in the desert. It’s in this diary that she lets him know that she and Max eventually got married.
Overall, it is a perfect ending to this underrated series.
