She has a big heart already, but having a baby would intensify that. She would also become more assertive in making sure Puck is fully involved in the baby's life. She doesn't want to be a single mother, so she'll push Puck to step up and be a good dad. And they would both learn to sacrifice some of their own wants for the sake of their new family.
