Doctor Who's Osgood is about to have another run in with the Zygons - and she won't be the only one. It appears the shape shifting aliens will have their sights set on the children of Britain.

The previously deceased UNIT scientist will find her genetic code copied once more during episodes 7 and 8, according to Doctor Who TV, an event that will surly give viewers "Day of the Doctor." While Twelve and Clara will certainly have their hands full with a seemingly revived Osgood, the Time Lord and his companion will spend a little time hanging out at a local park, working to draw Earth's latest invaders out of their child-sized disguises (see photos here).

Penned by Peter Harness, the two-part episode will leave viewers with one of the season's most intense cliffhangers.

"It's nice to do a cliffhanger," Harness teased, according to Digital Spy. "And I tried to do the biggest cliffhanger I possibly could."

It is unclear whether or not this white-knuckle episode 7 conclusion will deal with Osgood, the children, or Clara's decision to wield a bazooka.
