Heads up (spoilerphobe) flisties!!
There's a mighty big casting spoiler about at the moment. It's seems that because this info is considered unavoidable it has been made...um...unavoidable.
I'm living with...
1) I knew that anyway and 2) we don't know how or why (and I am REALLY hoping to remain unspoiled about that).
And if you don't know what I'm talking about then you've remained (remarkably) unspoiled. The only way to remain so will be to avoid the nets for ages 'cause it'll be damn hard to not stumble across this one.
ETA: Actual spoiler is in the comments if you want to know what it is. ;)
