Greed's joining in to see if a certain Xingese idiot managed to get himself trapped in this thing or not. No preference on who he ends up going for, and even if he'll be pissed that they don't find Ling he'll probably just try to beat the tar out of whatever shadow appears to vent frustration over the situation.

As some may not know, Greed is a homunculus with super healing powers, and will be nearly-impossible to kill. He can also harden his skin until it's as hard as diamond, making it an effective shield and, in his hands, an effective weapon as well.
