would be "coming back with a whole new determination to get what she wants" and that "she didn't have any expectations set in stone, but it's always hard to see your first love with someone else". When Colleen returned, she acted as an obstacle in J.T.'s romance with Mackenzie Browning (then Rachel Kimsey). When Kimsey was let go and Mackenzie exited, J.T. and Colleen reunited, and another obstacle designed to break them up came in the form of a new character, Adrian Korbel (Eyal Podell). León theorized that while Colleen felt an attraction to Korbel, her heart belonged to J.T., saying: "She absolutely loves him and adores him, but she's going through that change where she was a little girl and now she's not. She's growing up and evolving. The bad boy was interesting to her when she was a teenager, but now she's more interested in the intellectual." Leon portrayed the character as confused while she conflicted between her love for J.T. and her attraction to Korbel. Colleen later cheated on J.T. with him, and they separated for the final time. Music Luckinbill's musical ability was utilized in J.T. and Colleen's storyline. He stated that the writers and producers felt like it would be a good idea. He added: "They wanted me to sing a song by Alison Krauss called, "When You Say Nothing at All". I liked it, was sitting at home one night working on that song and this new song just came about." The new song Luckinbill wrote was entitled "Feel". In writing the song, Luckinbill said he was "thinking of the character's viewpoint, from J.T. to Colleen. If he were going to write her a song, what would he write? And these words came out. I ended up writing a song that night, which I took to our producers and said, 'I know you want me to sing this song, but how do you feel about this one? It's character driven.'" Smith decided Luckinbill would sing both "Feel" and "When You Say Nothing at All". Luckinbill sang Krauss' song on the episode dated December 26, 2002, where J.T. serenades Colleen on her sixteenth birthday. Smith wrote a scene specifically for the song Luckinbill wrote, featuring J.T. playing his guitar at Colleen's Valentine's Day dance where he performed "Feel". After J.T. cheats on Colleen with Anita, Luckinbill wrote an untitled song in character for the show
