Jenny Everywhere Day 2015 - ACE Rules OK!
Jenny Everywhere is having some fun with the Doctor. She's stolen the 4th Doctor's scarf, and as a tribute to her friend (and ex-companion to the 7th Doctor) painted ACE RULES OK! on the TARDIS. The 13th Doctor doesn't look too impressed, but Clara takes it as the joke it is.
