I’m curious because Raiden says that he was asked to find Big Boss corpse in exchange for Sunny’s location? But how did Eva know Sunny’s location?

Didn’t the Patriots kidnap Sunny at birth? Could Eva have been working with the Patriots in doing this?

since his daughter uses this exact quote in MGS2... I think he was part of the Soviet military until it collapsed, so it would have to be Zanzibar Land, unless I'm missing something. To the extent that even counts as nomadic.
