Another question: How old can Edea be? Would her age fit with a 18 years old son? In Cids case it definitely would

Perhaps Seifer knew about the realtionship and Cid was always like a father to Squall. Maybe Seifer was jealous...

I dont know all the cards, but a few ones

Squall - Laguna
Cifer - Cid
Quistis - her fanclub
Selphie - her best friend in Trabia
Irvine - Dobe of FH
Rinoa - General Carway
Xell - His adoptive mother Din

So we knew, that almost the ones have cards from these listed people standing in a strong relationship to them... what about Irvine ?
