Sadie

Sadie is a pediatric patient who couldn't be discharged until she had a bowel movement.

History
Sadie was in the hospital presumably after having had surgery. She talked to Alex, who said she couldn't be released until after she had a bowel movement, which she had not. The next day, she informed him that she'd finally had a bowel movement, so he said she could be discharged.

Professional
She got along well with Alex Karev. She called him Alex over his objections, saying she'd call him Dr. Karev when he said she could go home.
