I'm quite certain Larry wasn't in the original Christmas story. The original Christmas story mainly involves characters like Mary, Joseph, the baby Jesus, the shepherds, and the three wise men. There's no mention of anyone named Larry in the traditional accounts of the nativity.
I don't really know. It depends on the specific details and characters of that particular story. You might need to go through it carefully to determine if Larry Novak is included.
I'm not certain who Larry Novak is without more context. He could be the author who created this original Christmas story, or perhaps a character within the story itself.
