I get why they didn't want to show a cross tattoo since that's monotheistic. You could explain it away that it means something else in the Colonies but then we'd probably complain about that too. I think having an overlay that brings it in line with the world was a better idea than trying to use make up and band aids to cover it.

I don't know anything about television except how to watch it so I have no idea why they'd flip. I might have to spend osme time rewatching Scar to see if I can figure it out. ;-)
