Exegesis is a strong word for theorycrafting. People want to know what happened to Raine. Just look for similar patterns across the games and extrapolate. Clearly, Raine was captured by Esthar androids and turned into a magicite capsule by Mother Brain in an alternate 1999. But then Noel (Leon spelled Backwards) traveled the History Crux and changed the timeline. Causing a time crash, splitting the world into the worlds of Balance and Ru'aun before Noel was born, resulting in an "equivalent" named "Leon" also known as "Squall"

Which means, Squall isn't technically Laguna's son per se, but Squall exists because Laguna had a son. This allows Squall to exist in the future of compressed time, the "algorithm" can't compress a "time orphan" -- unique instances that are the result of a paradox.
Moreover, Squall father was likely the G.F. Griever who was possessed by Ultima and became SIN.
