Forum:Why don't Klaus's friends trust him?

Klaus Wolfenbach used to be best friends with the Heterodyne Boys so why do his former fiends no longer trust him. Barry left when Agatha was 8 so he had to have been around when Klaus returned and began his take over so why didn’t he get in touch with him. The same goes for Punch, Judy, and Dr. Beetle. My guess is that some time during the Other War Lucrezia decided to take advantage of the fact that Klaus was gone and use him as a scape goat. She left evidence that Klaus was or at least worked for the Other. The fact that Klaus is not the most diplomatic of people and his take over of Europa must have convinced the others that the evidence was true. This would explain why his old comrades didn’t trust him and kept Agatha a secret from him.
