<P> The original storyline designed for J.T. and Colleen centered around an unrequited crush she feels for him . Luckinbill and Fonseca, the first actress to portray Colleen, thought their character's relationship would progress no further than friendship . Fonseca said that if they became a couple, the fun brought on by the "tug - and - pull" element between them could disappear . Luckinbill considered the age difference too great an obstacle to overcome, as at the time, J.T. was 18 years old and Colleen was 15 . Smith later pushed for the plot to be taken further and the characters were paired romantically . Both soap opera critics and members of the show's cast and crew considered this a controversial and surprising move . Fonseca stated she "wasn't expecting it at all", and admitted that even former executive producer David Shaughnessy found the pairing "shocking". </P> <P> The writers used J.T.'s relationship with Colleen to bring out a more sympathetic side to him that the audience up to that point never witnessed before . Smith characterized their storyline as "taking this guy on the journey from wild college kid to being in love with this little high school sophomore". They also positioned Colleen as the aggressor in the relationship by scripting her as pursuing J.T., while he, in an uncharacteristic move, held off because of the difference in their ages . The writers "carefully navigated the development of this relationship, emphasizing its tender, supportive aspects ." They scripted them as "ferociously protective" of each other . </P> <P> For the scenes leading up to Colleen's death, The Young and the Restless went on location to Franklin Canyon, California . The inside of the lake that Colleen drowns in was recreated in the CBS Studios . The Bold and the Beautiful's head writer and executive producer Bradley Bell allowed Don Diamont to return to The Young and the Restless as Colleen's deceased father, Brad, as one of the visions Colleen has while unconscious . Diamont currently portrays The Bold and the Beautiful's Bill Spencer, Jr . "In order to accommodate contract constraints and actors' availability, we were writing scenes that were shot the following week, which is very unusual," said The Young and the Restless's co-headwriter Scott Hamner . "The appearance of Don gave a depth of feeling to the show that would not have been possible without him ." During the taping of Colleen's final scenes, Sursok was not there . "They had to use insert shots of me (which were filmed beforehand) for when she was shown in bed at the hospital," she said . </P> <P> After returning to town with her mother, Colleen became friends with local girls Lily Winters and Sierra Hoffman, and begins a romance with J.T. Hellstrom . At first, Colleen's family was wary of J.T. as he had a bad track record with women, but they eventually accepted the relationship . Sex became a stumbling block for the couple . Colleen made sexual overtures to J.T. and he turned her down because of their age difference . Not long afterward, he gave in to the advances of an older woman, Anita Hodges . When Colleen found out, she was devastated and the two broke up, though however they reconciled soon after . </P>
