Rigsy’s TARDIS art for Clara is a beautiful thing:
So much detail, so much love here. He knew her only briefly, but like the Doctor, she blazed into his life and left a mark that will never fade. More than that: she gave her life for his. Learning that he was never in danger, while her act sealed her fate, only compounds the irony and hollowness of her death. Rigsy will move on, but he will never, ever forget.
