In early 2012, Spinelli moves in with Maxie when she needs a roommate, in hopes of winning her back. Maxie confesses to killing Lisa Niles because she feels guilty about her cousin Robin Scorpio's death. Maxie is sent to prison, and when Spinelli uncovers evidence that proves Matt is the true killer, Maxie urges him to keep her secret. Spinelli reveals the truth and Maxie tells him she will never forgive him. Maxie marries Matt so she won't have to testify against him, but Matt confesses and is sent to prison. Maxie eventually forgives Spinelli and wants to be friends, but Spinelli cuts her out of his life. Spinelli is hired by Olivia Falconeri in June to investigate Heather Webber, leading to Heather's arrest.
