I didn't really know what to title this, I wrote this because a lot of people think the Pizza vs. Ice cream decision is Luke or Kenny.
Christa or Kenny: Christa took care of you for 16 months, but Kenny is willing to put his life on the line for you. Probably the most likely to happen.
My choice: Christa
Bonnie or Sarita: While not major characters, they both appeal to me in the same way and would be a tough decision.
My choice: really difficult but Sarita
Sarah or the baby: Sarah's made some mistakes in the past, the baby is just young, innocent and needs caring, both are big liabilities but Sarah could quickly learn how to fight later on. I don't see this one happening though since someone should always be watching the baby and if the baby was bitten it'd pretty much immediately die.
My choice: The baby
Write what you would choose and if you want write some of your own.
