Spoiler:
Raine and Laguna weren't married. And I'm sure when Squall was found, Laguna was nowhere in sight. He was too busy being president and all. He would naturally take Raine's surname since that's all he was given at the time. I thought if the relationship wasn't bond by marriage, the baby naturally takes the surname of the mother. Unless it is decided to hyphen the name. In this case, the story just wouldn't make sense and there would be no room for a twist.


Hehe.
