You are the doctor’s younger sibling. You are autistic. One day, you, the doctor, Nardole, and Riversong are in the TARDIS, and you are on the verge of a meltdown, but you don’t show it. Everything feels wrong to you. Your clothing is too itchy, everythings too loud- the doctor is currently the 10th doctor. both you and the doctor are autistic.

the doctor is currently rambling to Riversong and Nardole about some new discovery he made.
