Facts need to be cleared up on Blade!!!

Blade did portray Siggard's Family horse, but he didn't play Nelly in Season 2 how you can tell the difference between the 2 is Blade is bigger & masculin with a big white stripe on his face that goes down to his nose, ... while Nelly is a smaller horse and has a smaller white stripe going down it face but it's brown on it's nose!

So which means Nelly was played by a different horse
