It's the coldest planet Yasmin has ever been on. That she can remember.
"Yaz!" the Doctor shouts, climbing an icy boulder. "Yaz! Look at this! It's NOT snow—!" In the middle of declaring this, she hesitates, noticing Yasmin clench her teeth and shiver in a dark faux-leather jacket.
A rainbow-bright scarf loops over Yasmin's neck and face.
"Why didn't you tell me…?" the Doctor whisper-scolds. "You humans…"
She doesn't wait for an explanation, pulling off her coat and arranging it on Yasmin's shoulders until the Doctor is satisfied. Yasmin rests her head against her, shiver-laughing, hugging arms to the Doctor's waist.
