RF Walden: "Alright who the hell drugged me this time-" Wally: "Why are you all taller than me..? Beach town: "...I must have hit my head on a rock after that last wave-" Opposite: "Why do you all look like me but uglier?" Watcher: "Oh dear" Avian: His wings spread in alarm "Who the fuck- where-" Killer: He's Shaking Grey-scale: "..do I question..?" Butcher: He hides his knife Actor: "Where the hell am I?!"
