Mimmi offers to help him and he gets into the program with her help.

His interest in her grows as Mimmi demonstrates more of her connection with dolphins and he becomes keen to get to know her more.
Eventually, Chris pucks up the courage to ask Mimmi out on a date and she happily accepts. Although the date goes great at first, it is spoiled by Ondina who is worried Chris will break Mimmi's heart the way Erik broke her heart and summons a rain storm. Mimmi is then forced to flee to avoid him seeing her as a mermaid. Believing that Mimmi left because she does not like him, Chris is left disappointed but accepting of the situation. However, things fall into place when Mimmi and Chris later attend a party at the cafe. The two admit their feelings for one another and finally become a couple.
At some point off screen, Chris is introduced to Zac by Mimmi. Although, he is unaware that Zac is Mimmi's brother, Chris does notice how close to one another they are and has no problem with it. Zac in return, is happy that Mimmi has found a nice boyfriend of her own in Chris and they are both friendly with one another. However, Chris and Mimmi's relationship is strained when Chris grows bothered by Mimmi's apparent secrecy. As Mimmi continues to deal with the threat of the dragon and her growing belief that her mother is alive, she finds herself ditching dates with Chris such as watching a football game Chris played in and attending a book signing event with him where he sees her get thrown out. Although trying to be understanding and patient, Chris cannot help but be frustrated further when Mimmi is unable to give straight answers to him on why she left as he is starting to believe Mimmi does not really like him. He also grows continually suspicious that Mimmi is hiding something from him. Chris later talks to Zac hoping to get some answers from him since he knows how close they are. Zac tries to insist that Chris is overthinking things, but Chris is left unsatisfied with their discussion. When Chris next sees Mimmi and asks him what happened at book signing, Mimmi still refuses to tell him the truth. Fed up with her lack of honesty, Chris breaks up with Mimmi, leaving her heartbroken.
