He’s mad that Peachy called him Paedowang and is threatening to bring the big guns out ( his alter ego Rotwang )
I almost shot my drink out my nose. The great and powerful Rotwang was just another one of Danger's pets at Brawl Hall, no one of consequence and certainly not someone who still gets added to the majority of legends lists, and furthermore, if Peaches just keeps to his usual level-headed posting style, the old Aussie fool will be frothing with rage inside of 3 pages or he'll be issuing one of his trademark tighty whiteys on a stick in surrender.... at which point he'll claim to "not be a flamer".... again.
On that note, it's quite startling how quickly his big gun alter ego disappears once he's had his ass handed to him. I know where the bodies are buried and all the skeletons in Rotty's closet. He's no more a threat online or off than a rainy Autumn day.
