Summary: The Doctor is left literally holding the baby.
“What am I going to do with you?”
It was a rhetorical question, since the being the Doctor was referring to was at present far too young to reply. It simply gazed up at him with a big, innocent blue eye, and sucked on a tentacle.
Martha frowned at the Doctor. “You’d better not be considering just leaving… it.” Alien it might be, but it was only a baby, unable to care for itself. “We have to find the family, or someone who can raise it.”
“And we will. I just never expected to be foster parent to a squidlet.”
