I predict that
Eomer will actually become a werewolf one day!
We'll know this when his posts start to look a little strange, i.e. he can't hit the keys properly with wolf paws...
The phantom will kill
Gil-gallad [
EDIT: and vice verca] because no one else could be bothered. And
The Barrow Wight will never give the sight to anyone; he'll continue to run it when he's old and grey with a beard the size of the Downs themselves.
The Guy who be short will turn out to be a stone giant and throw rocks at us all. Also,
Sleepy Ranger will finally admit to being a narcoleptic, to the surprise of no one. And
Morsul the Dark will turn out to be quite a bright chap.
And of course,
Hookbill the Goomba will have been driven out of town for posting on Crazy captions too often.
