Jay Harmer is an 18 year old male recently featured in the GTA V videos titled "Literally Cancer" and "Two More".

He first came in contact with Nerd3 through Starlight Childrens Foundation at the age of 15, during or after having survived cancer. The two were supposed to meet to play video games together. However, the meet sadly had to be postponed, as Jay's cancer resurfaced before it could take place.

Three years later, he had beaten the cancer for a second time. In February of 2017, at the age of 18, his wish finally came true, and he got to meet and play GTA together with Daniel and Matt.

On March 10th, a video entitled "Nerd3 is in Hospital" was uploaded to the Nerd3 channel. In it, Jay reveals that he is back in the hospital, as his cancer has returned for a third time. He also says that no treatments are working, and that he is not expected to live much longer. Despite the circumstances, Jay remains cheerful, and even encourages everyone to send him jokes about his situation.
