Nick was the older brother of Matty, the patient in the Season 3 episode Family. He was portrayed by actor Jascha Washington. Nick was suffering from leukemia and needed a bone marrow transplant. Luckily, Matty was a perfect 6/6 match. Nick was given radiation therapy to destroy his remainign diseased bone marrow and was put in a clean room pending the procedure. Unfortunately, just as the procedure was ready to proceed, Matty started to sneeze and Wilson realized that if Nick got a disease from Matty in the transplant, it would ravage his weakened immune system.
