Shane and Teddy begin dating and eventually have a Las Vegas wedding, albeit unofficial. However, Silver accidentally sends the wedding video to Marissa Harris-Young's campaign and it ends up on the news, ruining Charles's chances at winning the election. Teddy believes it to be Shane who leaked the video, but finds out the truth from Silver.
Teddy shows up at the West Beverly Hills High School alumni event stating that Shane had broken up with him, though Shane arrives shortly after him and states that Teddy ran away and won't return his calls. Silver works out their issues for Teddy's sake and the two reunite.
However, after Teddy and Silver reveal they will be having a baby together, Shane is not supportive and threatens to sue Silver if she goes through with the insemination.
