Well, this Harrison fellow may have all those animals, Katie has seen some of them, but how many he has?, how many he has sold?, is he selling more hets than he has? etc., aside,
I would say it's obvious he put one over on Katie. From the looks of that posted verification, he does keep photo records, so he should have been able to tell if the returned BP's were the same as the ones he sent. I think he had to know they weren't the same ones, so giving Katie that....."they have a 50/50 chance" garbage, was just so he could get a better price, after he knew he had been ripped off. I would bet money they are normals. Period.
I mean, we all knew that the returned snakes were or were not the same ones, and we knew that for Harrison to equate that to, "50% chance they are hets", was the stupidest, most illogical rational, but know we know for a fact he has photo ID's so he had to know.
