|Ding, dong, bitches!|
The brothers Winchester are trying to rig up a system in the Men Of Letters' Batcave to track the fallen angels, but in the process unearth the bunker's supercomputer. Having no idea how it works they call in tech support - the form of Charlie Bradbury (Felicia Day).
However, while doing all this they accidentally free a hunter, trapped magically since the 1930s, who turns out to be Dorothy (Tiio Horn) ... as in Wizard Of Oz Dorothy.
And she wasn't alone: she had imprisoned herself in a binding spell with the indestructible Wicked Witch Of The West (Maya Massar), who is now loose in the bunker and hunting a magical key to get herself back to Oz.
On paper, Slumber Party sounds quite groan-worthy. The Supernatural universe is quite firm, but can it stand being linked to the perceived fripperies of Oz?
As it happens, the episode wasn't anywhere near as bad as it could have been.
A bottle episode, set entirely within the confines of the bunker, Slumber Party had some snappy dialogue (as well as some clunkers), a few references to past episodes and some interesting ideas.
But I have to wonder - especially given the ending and the fact that I'm pretty certain Charlie is coming back - is Oz going to become a fixture of the Supernatural 'verse now or will it be swept under the carpet and forgotten like The Thule Society (from Everybody Hates Hitler)?
And if Oz is 'real', what about other public domain 'fantasy locations' - or fairy realms - such as Wonderland?
While the inciting incident of Slumber Party was very much part of the season's story arc, the rest of the episode felt rather like filler. Ultimately, its importance will only come to light later on if the doors this story opens are ever referenced again.
