[Joseph Jostar]

It's six am and I was trying to confirm this on a somewhat high-CEL character, so forgive any mistakes, but as far as I can tell the Shades created use your character name rather than their alias (if in use), making it a simple matter to mouseover them if you're not an NPC. On top of that, when you Shuffle with them, if the tile you're moved to is within one square of your original location (including diagonally), you'll glide to the location as BYOND mobs are wont to do, making it painfully obvious where you've just wound up.
