Fast.. why didn't she want to go fast? Fall off? Couldn't she hold on. Sure she couldn't easily dig her nails in to crystal.. but didn't he have enough jagged edges that she'd be able to grip them? Even his mane. That should've been something good to hold on to. Surely it'd be easy enough to get a nice firm grip on. "You... Don't like going fast..?" Kh're asked, his words slowed down a bit and his voice not as chipper as usual although it didn't lose much of it.
"It'd be safer for all of us to walk. With you running about like crazy there's no telling who or what you'd run in to, or if you might make a movement that makes Miss Elindess fall down and get hurt. It'd be quite the fall for her from your back to the floor." Yerenthor tried to explain it as soon as possible, knowing that it'd probably help her out a lot.
Sadly, it didn't seem like Kh're had paid him much attention. Sure, he had been listening and had even heard him. Just would rather hear things from the Teigu instead. It was her that he had offered the ride to after all, not Yere.
