"Get out of my way, Laine," you say. "I just killed someone more important than you. I can kill you too." Laine doesn't look fazed. "I'm not taking threats from a two-bit gnoll-killer like you," he says. "Or maybe you're worth more than two bits now. Did you even keep the bounty you earned from the gnoll king before you came here? Or did you first spend it all at the Lion's Pride Inn drinking yourself dumb in celebration?"
Dodge past him and leave. See what Laine has in mind. Threatening him isn't working. Take another option.
