Nick wrote a song for Penny, but she thought he wrote it for her to sing. When he realizes she has a boyfriend, he leaves her gig early, deeply hurt. However, he still lets her record the song with him, and is pleased when he finds out that she is now single, having broken up with her boyfriend ("Wrong Song.")
He had a short lived crush on Maria, the pizza girl along with Kevin and Joe. Nick tried to impress her by singing her a song they wrote for her. She was freaked out by them all fighting over her, and eventually they realised they didn't know anything about her to be fighting over her ("Slice of Life.")
There was no relationship between Nick and Macy in the first season, however there were a few moments where the two looked at each other. Also, in Love Sick, Nick calls her a genius.
In House Party, Nick hugs her when he sees her, and says that it's good to see her. In Back to the Beach, Nick gets jealous when a surfer suggests he'd like to spend more time with Macy, and tries to stop this from happening by saying she isn't interested. In And... Action! while Nick teaches Macy how to play guitar they both hint that they would like to be more than friends with each other. In The Secret, Nick and Macy try to keep their new relationship from the others. Also in this episode, Nick writes and performs a song for Macy entitled "Your Biggest Fan". Nick and Macy celebrated their "One Month-a-Versary" in Up In The Air. The sub plot of this episode is Nick and Kevin attempting to find the perfect gift for Macy. An on-screen kiss was filmed for the The Secret, but due to Disney's "one kiss per season" policy, it was dropped from the episode in favor of Joe and Stella's in Band of Brothers. Direct and executive producer, Paul Hoen, tweeted a picture confirming that kiss actually happened. (See Also: Nacy)
