Are Midgardian horses really that fragile about tiredness too? He asked Bar about the potential injury risks of a human falling off a horse from a halt or a slow speed, and the dangers to a horse of it spooking, but he didn't think to ask about fatigue.

It's a serious question. It seems excessive to him, and they did have a prior quarrel -- the horse was a pretext for both of them, said Hotspur -- but it matters, whether he struck out in temper or in fear for another.
