Kim Merring

Kim Merring is one of the four sisters who repeatedly turned blue.

History
Kim came to the practice with her mother when her sister's skin turned cornflower blue. After looking for possible causes, Cooper found out that Erin had recently had her first ever cavity filled at the dentist and believed the dental drugs had reacted with the hemoglobin in her blood, which had turned her blue. He gave her methylene blue to make her pink again and sent her home. However, she came back and was blue again, along with her three sisters.

After giving them all methylene blue, Cooper went to their house to look for environment poisons, but found nothing. While he was there, Erin had a seizure and had to rushed to the hospital. Desperate to find an answer, Cooper went back to the house and pretended to be a princess with Becky, Kim, and Sasha, and they led him to their castle, which was a shed that had bags of fertilizer with ammonium nitrate in it, which was poisoning them.

Familial
Kim is very close with her three sisters. The four of them play princesses, which included going into a castle together. They rarely speak to adults.
