Laura Mercer is J.P.'s older sister, introduced in the seventh episode of the first season, "Sunday Clothes". She is an adult who still lives at home while working as a nurse and also appears to help take care of the family.

Physical appearance

Laura is pale with red hair and black beady eyes, just like her brother, J.P..

She has full, black eyelashes and her hair is typically held back with a ponytail and a white hair clip.


Laura seems to be very strong, responsible, sassy, blunt, and still clearly loves her brother a lot. She has also been shown to be a body-positive person, referring to J.P.'s body as "beautiful" on more than one occasion.
