Strangely, Peter has no father in his family tree, which simply shows Dora as his mother. This has led some players to believe that he was adopted or born out-of-wedlock. Dora has the lifetime want to "Have 6 Grandchildren". When the game starts, she already has three - David, Sharla and Tommy - and she will not die of old age before Samantha's twins are born. However, since there is a bug in game, Peter will not be the actual father, and Dora will not be the grandmother of the twins. This will be fixed if the game is patched.
