Saturday night, we'll be getting an Amy-centric episode of Doctor Who. It's titled "The Girl Who Waited," which as you might remember is a nickname assigned to Amy by the Doctor (the Doctor has also described Amy's husband, Rory, as "The Boy Who Waited").
In the episode, according to the press release, "Amy is trapped in a quarantine facility for victims of an alien plague – a plague that will kill the Doctor in a day. The Doctor can use the TARDIS to smash through time and break in, but then Rory is on his own. He must find Amy and bring her back to the TARDIS before the alien doctors can administer their medicine. Rory is about to encounter a very different side to his wife. Can he rescue Amy before she is killed by kindness?"
From the trailer at the end of "Night Terrors," we've learned that Amy is stuck in a different time stream from Rory and the Doctor, and that -- somehow -- there end up being two Amys in the episode... one of them significantly older than the other.
"The Girl Who Waited" will air Saturday on BBC1 in the UK and BBC America in the US. Check out some promo photos from the episode below.
