well, may as it be, horse get out of the ways unscated for liadrin, which basically means that either Loial is more useless that it is in the show (since they brought him just because he knew the way) or either Loial is a Liar (which would be really troubling)

I would also like to add the fact that in Season 01 Episode 6 Loial states specifically that horses wont survive the ways (change from the book), but then Liandrim bring horses into the ways to dispatch the unconscious girls (another change from the books). Poor poor writing
