"Little girl, come here!"
Emma watched in horror as the Doctor started to chase down a girl who was no older than eight. "Doctor, this doesn't look good!" She ran after him. He didn't even pay attention to her, instead grabbing onto the girl's shoulder.
"Little girl, we just want to help. Has anything strange-" He was cut off by the girl spinning around, blowing on a whistle that was attached to a chain around her neck. "Alright, that's a bit-"
"Stranger danger!" She screamed.
"Oh, my God, Doctor!" Emma didn't have time to leap forward before the girl aimed a kick right between the Doctor's legs. "Ooh." She grimaced. The girl ran off, leaving the Doctor to fall to his knees, face etched with pain. "Doctor, are - are you alright?" She cautiously approached him.
"Yes, of course, perfectly fine." He squeaked out, his jaw clenched.
A small laugh escaped her lips and she faked a cough to cover it up, but his glare told her that he heard. "Sorry! It's just that..." She burst into laughter then, one hand clutching her stomach as she bent over. "You - you got kicked...in the crotch...by a seven year old girl!"
"Yes, yes, laugh your heart out." He took a deep breath. "Help me up, will you?" Still laughing, she grabbed his hands and pulled him to his feet.
"Can you walk?" She giggled.
"Yeah, I can walk. Shut up."
As they walked back to the TARDIS, her laughing and him scowling, he reached out and shoved her into some nearby bushes.
