Zane first appears in the second season episode, "E=MC...?" He is arrested for crashing the New York Stock Exchange, but rather than sending him to jail, the authorities decide that he would be useful to the town of Eureka. Upon his arrival, he helps avert a disaster brought on by an out-of-control experiment to recreate the Big Bang. Although he's tried more to behave himself, he is still constantly getting into trouble.
Relationship with Jo Lupo
Upon his initial arrival to Eureka, Jo Lupo and Zane have chemistry. They hit some rough patches early on when he says something that makes her feel dumb because she's not a scientist like most Eureka residents and he's less than understanding about her belief in God. The pair work past these issues and are in an unsteady, yet budding relationship.
However, in Episode 1 of Season 4, Zane works up the courage to ask Jo to marry him, only to be left hanging when Jo is unable to give him an answer. Jo is then whisked away to the past with a few other characters. At the end of the episode, when Jo returns from the past, she heads to the jail only to find Zane sitting on the bunk behind bars. Trying to finally tell him she will marry him, she is shocked to find that in this alternate time, she and Zane are not an item; and Zane is currently a mischievous troublemaker whose antics constantly cause him to end up in Carter's jail. The audience and Jo later learn that in the new timeline, Zane is dating Sheriff Carter's daughter, Zoe. While in the episode "The Ex-Files" the audience is shown that he is dating Zoe just to annoy Carter, and then led to believe that he's actually interested in Jo, it later becomes apparent that this was said by Jo's hallucination of the Zane she knew in the other timeline and not the real Zane. When Jo gives him back the engagement ring she got from him before the alternate timeline, Zane's response is, "Why do you have my grandmother's ring?", making Jo realize she wasn't talking to the hallucination like she thought she was. At the end of the mid season premiere Zane puts the pieces together and realized something is going on. He then confronts Jo and asks what they were to each other before and she replies nothing. He is not convinced and kisses her, saying it didn't seem like a first kiss. Then Zoe walks in and invites Jo to celebrate with her and Zane. Jo refuses and leaves.
In the premiere of the second half of Season 4, Zane and Fargo get launched into space accidentally and Zane asks Fargo to tell him what's going on with Lupo, realizing that they once meant something to each other but he doesn't remember it but she does but she won't tell him. In the episode "Reprise," Fargo and Zane both later imply to Jo that Zane is now aware of the alternate timeline. Now knowing the truth, Zane is persistent in wanting to know what he and Jo were to each other, but she continually refuses because she is trying to let the relationship go. Zane argues that if they meant something to each other before, maybe they're still meant to be together on this timeline and they kiss. In the episode "Glimpse", Jack and Allison discover that Jo and Zane are sleeping together. Jack later finds out from Jo that this has been going on for "five or six weeks", although she says she is putting an end to it.
