SG: Sharp Eyed Viewers Notice Something Amiss

It's a trivial matter really, but this is what you get when you have only two episodes per week. There're two reasonings for this, one practical and the other's an explanation within the drama context. Which one would you prefer: A black-hearted Joo Won or a mere blooper?

As seen in Episode 9, the hearts drawn by Ra Im were clearly red; the color even visible from the back.

In the next episode the "fixed" map was already a copy, confirmed by the fact that the red in the hearts are now black hearts. "It must have been a Photostatted copy and recolored with red," viewers mused.

But some think: Could it be that Joo Won darkened them while adding the word "coward"? That's Kim Joo Won for you!

Chloe Says: I'm inclined to believe the earlier than the latter; if Joo Won did in fact darken it, the camera wouldn't have missed that moment (panning on his gleeful expression, no doubt). And I don't think he's that petty, did he or did he not hang Oska socks on Christmas trees for Ra Im?
