I got a verry tricky question now... I noticed in many cartoons * including gargoyles * that reruns always differ from the first time they pass on tv. ( I'm french and having trouble making that question clear... omg !!! )
Ok ok... here's an example :
in the episode Awakening 2, when Xanatos's *employees* attack the castle... one of them throws a granade at Goliath and Hudson I beleive... he shouted :"CATCH".
When that episode played again on tv the voice wasn't the same and he didn't shouted it.

Same thing with the "MOVE NOW" of Awakening 1.

How come ??? * do they record the sound twice or do they correct things they don't like after showing it once ??? )

sorry for the long question. You forgive me ?
