Carter and Lucy eventually come to an agreement after the episode "The Good Fight" when the pair spend a day and evening searching for a little girl's father who has the same extremely rare blood type as she does.

Although the pair find the father, the girl's condition remains critical and it is not clear whether the blood donation came in time to help save her.

[2] During the episode The Storm: Part 1, Lucy accidentally kicks Carter while performing a work-out video with a patient in an exam room; he suffers a gash on his head.

The pair later share a kiss in the x-ray room, but Carter ends their brief relationship because it is unethical for medical students and their residents to be romantically involved.

This is the first time the show has a main character who starts out working in the ER but is shown to be a poor match for emergency medicine and a good match instead for a different medical field (a similar, longer path is traced starting in Season 10 for Neela Rasgotra, who is an uneven ER doctor but emerges over time as a superb surgeon).

Lucy's role in the early episodes of season 6 is rather small, having only minor sub plots such as helping a young artist who is using cocaine and urging Dr. Dave Malucci to come forward and admit his possible mistake when using a Bunsen Burner that is thought to have caused an explosion in the ER.

Lucy goes above and beyond to ensure Valerie gets the life saving procedure - even going so far as to bang on Dr. Robert Romano's door in the middle of the night on Christmas Eve.

This makes her ponder her time at County General and prompts her to give a moving speech to Dr. Luka Kovac about it: "It's never been very easy for me to be here, sometimes I felt like I would never fit in.

On February 14, 2000, over the course of two episodes, "Be Still My Heart" and "All In The Family", Paul Sobriki (played by David Krumholtz), a man with schizophrenia, checks into the emergency room.

Lucy picks up on his mental problems, but Carter refuses to help her with the case and either ignores her accurate views of Paul's state or openly scoffs at them.

While in a delusional state, Paul acquires a knife that was to be used to cut a Valentine's Day cake and stabs Lucy multiple times before lying in wait for Carter.

When Carter enters the room and sees a Valentine for Lucy on the floor, he picks it up and looks over it smiling just as Paul emerges from the shadows and stabs him twice before fleeing.

Upon glancing at his blood-stained fingers, Carter goes into shock and hits the floor, gazing in surprise at Lucy lying in a pool of blood on the other side of the gurney.
