New Daddy

My mom and I took Mason out to lunch this afternoon, and he was chattering away as usual. Some of what he says is nonsense (like he just barely told me "When the sun comes up, we can have popcorn!"....), but if you pay close attention he's pretty funny sometimes.

Much to our surprise, he turned to my mom and said that we were "waiting for new daddy." During questioning, he said "old daddy is at the fire station" and that "new daddy is going to come sit right here by me."

When asked if he knew new daddy's name, he said yes. "It's Papa!"

He calls my dad Papa, so we were relieved that he wasn't calling my virtue into question; we're just trying to figure out Papa's "new" name. Anyone have any ideas?
