Amergan

Ghosts...? Zoinks, Scooby. This is something new. We've had demons in the series, but no ghosts so far as I know.

Who do you think Amergan might be a ghost of? Personally, I think it would be awesome if he was Methos' ghost, disguising himself for whatever reason. Yeah, he's dead and nobody can take his quickening, but I can see Methos having another secret up his sleeve. And Peter Wingfield *is* doing his voice...
