Undyne was quick to cool herself upon sight of her king. The boulder in her hands was quickly set down before the inevitability of it breaking within her grasp happened. Though she never said it to anyone, even Alphys, Undyne saw Asgore like a father figure. Since she was a monster kid, she had been trained by Asgore to become stronger and better. Most of her time was spent training, even back then, and when she finally knocked him to the ground, it didn't feel as good as she thought it would. The rush of victory wasn't there, only the knowledge that she had just hit King Asgore, a giant, fuzzy pushover. That made her feel guilty, somehow. Of course, she felt glad that she could beat him, but the reality of actually beating him did not settle well with her. Even after that, as she got stronger, her mind always wandered back to the same, horrible thought.

She wouldn't ever do it, though. She was physically incapable of doing so. There was no way on the entirety of the earth that she'd do something like that.

"Hey... King Asgore!"[/color] She had to pause and stop herself before the word even escaped her mouth. She wouldn't have so many people, especially her friends, hear that word coming out of her mouth and directed at Asgore. [color=003471]"So I'm not the only one going back to look for Frisk, that's good. I CAN'T JUST LEAVE MY BEST BUD AND BOSS TO BE CAPTURED OR HURT BY WHOEVER FUHUHU!"[/color] She laughed haughtily before launching one of her spears at the ground.
