Dr. Cleo Finch made her debut at the start of Season 6 as a skilled new pediatric fellow at County General Hospital.

While under Cleo's care, Reese accidentally injured his hand on a piano, leading Carla to claim she was untrustworthy and irresponsible.

Cleo took the stand to testify that she hoped to play an important role in both Peter and Reese's lives.

After winning his custody battle over Reese, Peter also departed the ER to work at the same hospital as Cleo.

[2] Michael Michele reprised her role as Dr. Finch in the Season 8 episode "On the Beach," at Mark Greene’s funeral, along with Eriq La Salle.
