I am reading "Ender's Game", and I can't figure out what it means when I come across this sentence.
Here is the context:
“Here, snag my hand!” Alai called.
Ender held out his hand. Alai took the shock of impact and helped Ender make a fairly gentle landing against the wall.
“That’s good,” Ender said. “We ought to practice that kind of thing.”
“That’s what I thought, only everybody’s turning to butter out there,” Alai said. “What happens if we get out there together? We should be able to shove each other in opposite directions.”
It was an admission that all might not be right between them. Is it OK for us to do something together? Ender’s answer was to take Alai by the wrist and get ready to push off.”
I think "all might not be right" could be a idiom, but find nothing when I google "all might not be right".
Or, "all might not be right" is a specific use of "all not" phrase? It is "all something might not be right between them. And that something is left out? And I can replace "all something might not be right" with "something might not all be right" without changing the meaning of the sentence?
