Graham O’Brien


 * “Oh, well, er, I had cancer and er... Well, strictly speaking, I'm still in remission, three years gone. And Grace was my chemo nurse. That's where we met and fell in love. So by rights, I shouldn't even be here.”
 * — Graham O’Brien

Graham O'Brien was a companion of the Thirteenth Doctor. He lived in Sheffield with his wife Grace and her grandson Ryan Sinclair.

Following the death of his wife, Graham chose to travel with the Doctor as a way of coping with his grief, rather than allowing it to consume him in a house filled with the memories she left behind. As part of Team TARDIS, Graham often served as a voice of common sense from the older era, while doubling as a proxy for the Doctor in times where women were not respected.
