While at school, Gar Logan was picked on for his green skin and hair. Jillian was the only one who was nice to him. They even began to date.

Their romance was cut short with the death of the doom patrol.

After the death of the doom patrol, Gar continued his acting job. The doom patrols' old enemy, Arsenal, came to take Gar's life but failed. Then, Gar's show was canceled.

While unemployed, Gar was reunited with Jillian. They began to date again. Her father was displeased by this because of Gar's appearance.

The arsenal came back and kidnapped Jillian. Gar found out that the Arsenal was actually his former guardian, Galtry, and he was the one to hire the original Arsenal to destroy the Doom Patrol. He was holding Jillian hostage to regain the money he had lost when Gar's guardianship was taken from him.

Gar called Vernon Questor, who was in charge of Steve Dayton's finances while Mento searched for who killed the Doom Patrol. He couldn't get the money for the ransom.

Galtry then put Beast Boy in an airtight room while he tried to get the money from Jillian's father. Beast boy escaped and defeated Galtry.

After that, Jillian's father sent her to Britian to continue her education. He did this to keep Jillian and Gar apart. She entered a rebellion stage. She dyed her hair pink.

After the betrayal and death of Terra, Jillian returned. She was able to heal some of the hurt he was feeling after Terra. They began to date once again.

A conflict with the Wilderbeast society turned the Titans upside down when a new girl came along. Her name was Terra and she looked just like the original. Athough, Gar was startled by her, he felt an undeniable attraction to her. This put a strain on her and Gar's relationship. After many attempts to save their relationship, Gar and Jillian's romance dissolved.
