The finale ended by Liam getting in extreme trouble after throwing himself at Jasper after him destroying his boat, which basically was his home as he was about to confess about the coins to his stepfather. The police came, and Liams fate is unknown. Naomi, in her pityness went to the school to be met by Canon, the man who she alleged raped her from the beginning, where he throws himself at her and most likely rapes her. Harry (Rob Estes) will no longer be featured in 90210 and was written out by the writers. In the ending of the episode, Harry got fired from his job since he saved Dixon from getting expelled, which led to an heated argument between Deb and Harry where one thing led to another and they came to the conclusion that they dont love eachother anymore. In the end of that scene, they were sitting at the dining table and playing around with their wedding bands, almost taking them off. My best bet would be that Harry is written out by leaving town and getting a divorce, considering he no longer has a job as the principal of west bev.
