"Eat this, Ass Butt," a golden voice purred from the nearest titan, just as a golden sword plunged outward from its chest, slicing up and down in a star pattern.
"Lucifer!" the Doctor growled curling up as yet another contraction spiked through his slim frame, "The baby's coming, I can't... "
"Sure you can, Doctor, just think of it as… a honey trap. Heck, it worked on me. Oh for Daddy's sake, haven't you ever played Portal?"
The Doctor stared up, confused, until another contraction stole all remaining breath from his gasping lungs.
"I DON'T THINK SO, LITTLE ONE, OFF WE GO NOW."
Lucifer's voice suddenly cut off, and the Doctor moaned as another round of contractions sliced through his concentration. A dark shadow bubbled out in a disk of black liquid from the bone titan stuck through with the sword, swallowing the sword and titan both in a crunch of blowback implosion.
"LITTLE TIME LORD, HAVE YOU POPPED YET? I SO LOOK FORWARD TO SUCKING THE JUICE FROM YOUR NEWBORN'S BONES!"
"Oh you little, you can't, I won't let… you… ow owowowowoowowowow AGGGGHHHHH!"
Thick bloody fluid suddenly oozed from between the Doctor's legs, and a large elephant masquerading as a baby plopped out from his body, drawing the headless mounds of the bone titans' full attention at the worst possible time.
