should there not be 3 Scots his son as a child and 2 Jack Frosts ??
See if anyone can follow along there should be the original Scott with his son as a child before he scared santa off the roof. The Scott that wished he was no longer Santa and Jack Frost hit him with a shovel and put on the Santa suit. The third Sott would be the one that tricked Jack Fost and restored history and put on the Santa suit after all.
The point I am making if there are 3 Scott's his son as a child and two Jack Frost, would they not have noticed noticed or heard each other some how.
