The last time Sam and Dean saw Charlie, she was off on a yellow-brick road adventure.

But on Supernatural Season 10 Episode 11, Charlie is back from Oz ... and things aren't looking quite so great for their friend.

In these preview photos of "There's No Place Like Home," it looks like the Charlie, Sam and Dean reunion isn't a super happy one.

And with a bright green light and that body on the ground, perhaps Charlie brought something with her when she came back from that magical land?
