"MONSTER!" "Kill it!" someone started; he seemed to remember this man being the mayor of Weaseltown or something…
Dipper panicked. Was he a monster? Did he not know?
He ran for the door, subconsciously shooting ice out behind him. He blocked the doorway with ten-foot-tall spikes and ran.
"Wait!" he heard. "That's my brother! Don't hurt him!"
His sister tried to chase him but she wasn't fast enough and it was to no avail. She and her fiancée chased him to the river, and he felt cornered until he stepped back and the water had frozen.
He tried it again, and it froze again. Therefore, he turned around and ran away from the castle.
His sister was crying. "It's my fault, I took his glove." she said.
Gabe hugged her. "It's not your fault. You had no way of knowing since he'd kept himself cooped up in his room for fifteen years."
"Sixteen." she sniffled. "I just thought…I thought he had a thing about dirt, or something."
At one point he turned around. Gabe-was that his name?-had made it very clear that he was not welcome back.
But his sister hadn't seen.
It began to snow, which was odd because it was summer. And it was snowing hard within ten minutes. They walked back up to the castle, and she never looked up once. His arm was around her shoulders.
She lifted her head. "I'm going after him."
"What?" Gabe said, clearly appalled.
"He's my brother, and this is my fault. I've got to fix it." she replied.
"Mabel, please, just let him go." Gabe told her.
She walked inside and grabbed her coat, demanding that they get her horse saddled and ready.
"Gabe, will you please be in charge of the kingdom until I get back?" she asked. Gabe gladly accepted, telling her that her every request would be fulfilled.
She made the announcement and began to ride off up towards the mountain.
The drawbridge was closed as soon as she was out of sight.
