This is a little spoilery since I waited until I played through the next couple of birthdays, so Linda and Kent are older here than they are currently in the story. Also, no one has LTWs locked in yet since I don't click on them and can't see whether they've made any choices.
So, should it be Clark:
His traits so far are: Insane, Couch Potato, Hydrophobic, and Easily Impressed. He's also first born and the only fairy child.
Or should it be Linda:
Her traits so far are: Insane, Loser, Friendly, and Can't Stand Art. She's a werewolf, middle child, and somehow came out purple.
Or should it be Kent:
His traits so far are: Insane, Genius, and Bookworm. He's also a werewolf and the baby of the family.
Vote over there on the side bar or leave me a comment with your choice! I'll leave the poll up for a week so that it will be all decided by the time I get a chance to play again.
