Hikaru's initial reaction to Honey is to pout, because that's not Kaoru. He gets over it quickly enough though and waves, his excitement over bringing home a dragon trumping his annoyance.

"Yep! I found him," he calls up proudly. He points Honey out helpfully, then, to Toothless; "That's Honey-senpai. If you ever wake him up, I'm not going to be responsible for what he does to you."

He then looks at the saddle on the dragon, then back to Honey, then back to the saddle. He's not stupid brave enough to try riding it, but maybe Honey would.
