Without any complaint, he moved in to take her place on the ice and she found herself silently pleased with his obedience. He might make a suitable squire for her- at least until her family found her, anyway. She watched as he collected himself and then pounced at the ice, and it made a much different sound in response to his weight than it had to hers, and she was impressed. Potentially even charmed. While he didn't crack the ice on his first attempt, she could have sworn she'd seen the entire surface of the stream bow down a little bit beneath his show of will and might. After a few more strikes, he'd managed to crack the surface, plunging forward following his momentum which brought him through the ice and into the water. Fortunately, the hole it too small, and the stream too shallow for it to present any risk of grabbing hold of him and carrying him beneath the ledge.
She was pleased further when he drew back, and offered her the right to drink first, even with a friendly smile on his lips. Her mood brightened significantly, to have found someone who knew how to treat nobility without having to be ordered around. So she moved forward with a graceful prowl and came to the edge of the gap in the ice. "Very well done," She purred. It wasn't exactly a thank you, but it wasn't in her nature to thank others for a service they were expected to provide. A compliment was generally hard-earned, and she felt as though her compliment had been more than gracious enough. She heeded his warning and crouched, gingerly, to drink from the waters. It was very cold- no wonder the ice had frozen so thick- but she was also very thirsty, and lapped it up without a moment of hesitation.
But after only a few sips, she felt an ache at the back of her mouth- at the very roof of it, she thought- that spread up and through her jaw and into what felt like her entire brain and eye cavities. "AhhhhhHHHHHHHH!" She complained, skittering backwards, her jaws hanging open, a few little water droplets dripping from her whiskers. She came to a halt in a crouch, her eyes squinted shut but watering at the corners as she felt the throbbing intensify from her brainfreeze. "Owwwowwwowwww-" She moaned, before she rediscovered just enough of her dignity to shout "DON'T LOOK AT ME!" pre-emptively before she continued to moan and whine, covering her muzzle with both of her paws as she begged for the cold, sudden shock of brainfreeze to subside. How humiliating.
