Things said by or about John Jones

Alice Obiefune: "He's grey. He's so grey he snuck on the TARDIS without anyone noticing. Even him!"

The Doctor: "There's a reason for that. He's an aberration. His cells. Something's strange there. The way they react to light. Constantly changing. It's like the world doesn't notice him. Yet." Doctor Who: The Eleventh Doctor #3.
