Camelot is determined to de-mystify the legend, to make it "real". Huh. Excalibur is a teen-aged girl, and she's trapped beneath the ice when Merlin freezes the lake and pokes a hole in the ice with the sword which Merlin takes from her, not Arthur. So much for the Lady in the Lake. The writers must have thought they were very clever, coming up with that "solution". I'm done with this show.
