It's one of those quiet nights in the TARDIS, so River Song is not in the mood for the Doctor's nonsense – especially when she's trying to sleep.
"What," She growls. "In God's name are you trying to do?"
The Doctor stands there, arms outstretched. "It's a hug. I give hugs now. Hugs are cool."
River laughs, stands, and pecks him on the cheek. "You are such a sweetie, but we can't hug yet."
"When?"
"Spoilers!" She winks, saunters out the room. The Doctor stares after her miserably.
"I thought that would go down better than the fez." He sighs.
