Greed activated "Devil's Nest Prisoner" on ??? but Failed
Alphonse or Edward used "Prodigy V2" to copy any Failed Action this Cycle (I think only Greed's Action failed so far)
"Roa" was activated on WU to reveal that Greed's Target was (Dr_Proffessor)
Edward used "Gatling Gun" on ??? and ??? but it triggered Greed's "Ultimate Legs"
Alphonse used "Iron Body Pacifist Soul" to convert ??? to Town (And as you said, it seems he targeted a Non-Town for sure)
So clearly there is something brewing between Elric Brothers & Greed
Conveniently Greed did indeed turn Ally later on in Story
And after all these Actions, we had this one:
Ling Yao (The New Greed in Story) used "The Good Prince" to copy 1 Town Ability
These Actions are extremely convenient, as if these Three are playing a Game of their own
Also how did "Roa" was used to check Greed's Target, aren't Invest Actions not allowed D0?
