Maybe the one on ST (the second one, let's call him the clone) was meant to be part of Time Twisted but traveled forward in time somehow. Now, since Ancient Greece existed way before Time Tangled was released, this guy still thinks he's on Time Twisted. Make sense? Now here's the idea. This guard would know about Monster Carnival, the original, since he he escaped before it was canceled. Keep an eye on him, he may be important to the quest of Monster Carnival.
(end extreme speculation)
