Envy has no idea what the hell's going on here as he watches the pair fight over their...seemingly very important but also very. Uh. Strange weapon.
He doesn't even know which one's dream this is, until the one vanishes, leaving the other to be consumed.
And maybe he's not really the type to help strangers, but he is the type to think that maybe he doesn't want to find out what happens if the person whose nightmare he's trapped in gets killed while he's still in it.
He tries to...well, swim, through the air in the direction of the kid, and if he can make it over there reaches out to attempt grabbing one of the strange creatures and flinging it off.
"Help me out here, I don't want to do all the work!"
