Dipper was usually so careful when venturing into the forest like this. He was filming for his next video-- nothing out of the ordinary. Well... except the content WAS a little more daring. His usual content was more daytime adventure and mystery focused, but he had been recently dared by many of his followers to film content in the dead of night.
He wasn't really scared by the idea, but after he had fallen and skinned his knee on a fallen tree about an hour prior, it seemed that he was some kind of beacon for these bloodthirsty maniacs. Weird.... he'd never even seen vampires in these woods. That was new.
Dipper was able to escape from them for a while, but just as he thought he'd gotten away, they had surrounded him. If they were literally anything else, at least he might be able to get some good filming content-- but if COURSE it would be vampires, one of the few creatures that don't show up on film. Dipper was searching for any way out, but alas, there was none.
Just as soon as he thought he was going to become vampire food, Bill showed up. Great... did he send these guys? Was he just waiting for Dipper to reach out and plead to be saved? Dipper cringed even thinking about it, but...
Dipper was definitely shocked. "--I- um- you saved me??"
Upon hearing the warning for them to not stick around there too long, he nodded."Y-yeah sure. Lets get out of here--"
He had no choice, really. It was either trust Bill or get attacked by vampires. At the moment, trusting Bill seemed like the better option.
