reunions
Their reunion in space was where Ellone told Laguna everything that had happened. Raine's death. Her own whereabouts and growing up on the White SeeD ship. The son he never knew about.
I have read a while back that some players never made the connection that Squall was the son of Laguna and Raine. While it wasn't flat out told to players, the connections were laid out. I did not have a problem connecting it as a 12 year old playing the game. Though I wish they did have a father and son conversation. Laguna and Squall never got to speak to eachother as father and son due to the events of the world at the time. If you speak to Ward and Kiros on the Ragnorak, they state the following:
After Squall and the party defeat Ultimecia, Laguna goes back home to Winhill and visit Raine's grave. He recalls the night that he proposed to her and how happy the two were.
Then, he sees Ellone with Kiros and Ward standing by from a distance. He gives her a small wave as the Balamb Garden flies by. Laguna kneels down and watch it fly off.
