He nods once, automatically keeping the less-scarred half of his face towards them as he smiles as warmly as he can. Crouching back down in the meadow grass, Sleet's elbows click, but he pays no mind, practically flattening his belly against the ground and rearranging his wings to make it easier for the little ones to climb aboard. 
"Some of my kids find it easier to hang onto my spines, if that would be easier for either of you," He tells them, clattering his neck spines lightly together to demonstrate what he means. He keeps his talons tucked under him, and his tail curled close to his side, hoping to put out the feeling that he's not about to lash out in any way.

Crystal
She was the more nervous one to climb onto Sleet, her brother climbing on before he did. Once he was on, she hesitantly followed. She accidentally dug her talons onto Sleet's scales, her ears flattening as she paused. She then quickly scrambled onto Sleet's back, hugging Blackout tightly. She was very scared and nervous, but as long as Blackout was there, she would be ok.

He climbed onto them with ease, grabbing onto one of the spikes, not pulling on it too hard. He noticed her sister's nervousness, and offered a wing for her to hide under. Once she was hiding under his wing, he sighed faintly, before lifting his head up. "We're ready to go. Please excuse my sister's nervousness. She's... Not too trustful of any adults really." He sighed, as if he understood why.

He can feel himself wince slightly at the feeling of little claws piercing at his hide, but stays still so they can both climb on without problem. It's just a little scratch; he's had worse from his kids at home, some of them actually aiming to draw blood. 
"'S alright," He reassures Blind Snow, peering at the two of them over his shoulder to make sure they're sturdy before standing up, slowly, fixing the position of his wings as he rises. 
"Nothin' to excuse," Sleet rumbles softly, shaking out his wings. "We all got our hangups; ain't nothin' to apologize for.
"Now, you two hold on tight, a'ight? Takeoff's the roughest part, but it'll be easy coasting when we get in the air." He flexes black claws into the dirt for a moment, adjusting his stance to compensate for the added weight between his shoulders. For the time being, Sleet doesn't ask whether or not they can fly. He's going to operate under the assumption that they can't, solely for the purpose of keeping himself prepared to catch one or both of them in case anything happens. 
"And- don't worry," He adds, giving them another look over his shoulder, that he *Hopes* Comes off as something comforting. "I won't let either of you fall, a'ight?" 
Sleet knows that the flight itself isn't what's making the little white dragonet nervous, but he figures he should let her keep her feelings to herself without having a big stranger trying to bully his way into uncovering them.
With that said, Sleet bunches his legs beneath him before launching out of the meadow, heavy weight and serrated claws leaving churned dirt where he had just been standing as his wings beat down hard, working to lift him and his passengers into the air as smoothly as possible.
