Gina is miles from home, and even further away from her goal of setting the world's bubble bath record. To survive on Felicity Island she's going to have to learn to do things for herself -- or else latch on to someone who will do them for her.
Gina Gibson only appears in The Sims Castaway Stories. She is one of the survivors of the sinking of the Queen Solomon. In her dialogue with the player character, she mentions wanting to get back home to her family - perhaps implying that she is married and/or has children, although this is not expanded upon.
After completing the Shipwrecked and Single story, Sandra and the other castaways will appear in the family bin because the helicopter that rescued them crashed. Her family bio implies that the crash was her fault. Gina is said to have taken over the helicopter control because she wanted to learn how to fly the helicopter, at which point it crashed.
