To the surprise of no one...
Knox has a soft appointment in the fall (when it's cooler, so less flies when there's a wound healing) to make someone a terrific gelding.
She said in the video that he is softly for sale even though they intend on keeping him until he is under saddle.
I don't think this is a huge surprise -- I'm in the very small Knox fan club, and even I'm ok with him being a great gelding for some one. I'm interested to see where he ends up! I think he's super cute and could make someone very happy, even if he's a little... Awkward right now 😂
