How can I be right when asking which one of two possibilities it is?

Putting semantics aside, I guess it's also possible that every Giant knows and they only hid it from Flare, but considering that she lived with them for a while I imagine that'd have been pretty hard.

The more people know a secret, the likelier it becomes that someones tounge slips at the wrong moment after all.
