James nodded, appreciating the gesture Lupin was making, but not quite understanding the motive. She was his enemy here, as far as he could tell, it was, after all, her father who he'd actively petitioned to be overthrown. Still, she was working to make his life, at least until sentencing, a little easier, which would make all the difference to how he had been treated in Azkaban.
"Thank you," he replied, his gaze locked on Khaat as he ignored the less organised members of the bench, fooling about as if they were on break.
"You know my arguments, I stated them during the last hearing before Ms. Lupin decided to ignore question raised by her colleagues," he explained, unable to resist the jab. "But I still fail to see exactly how I am guilty of the charges being brought against me. Yes, I worked with Gellert Grindelwald, however I was merely supporting a man I deemed more fit to rule the country than the incumbent, your father. Any politician could be standing where I stand at the moment for that very reason. Yes, Grindelwald's actions were illegal, there is no denying this, however mine were not," he argued, trying his best not to get worked up in his defence - maintaining a level head was of the essence here.
"Did I know the means Gellert would use to attain power?" He asked, "No, I did not. Had I known, I would doubtlessly abandoned him instantly in his attempts, however after he'd taken his position, I knew that it was my responsibility as a seasoned politician to remain in his good graces, for he needed assistance in running the country. Had I not aided him from that point onwards, the people of our great nation would have suffered all the more for my negligence."
This last part, at the very least, was the truth. Grindelwald had immediately gone off the rails after taking power in the Ministry, insisting on prosecuting everyone who criticised his regime, which, more or less, was everyone. He knew no bounds, whether it was a child or an adult working who simply made comment on something they did not like, he could immediately plan to destroy them. James had worked to keep this from happening, he'd worked to make sure that the statute of secrecy was maintained, and he'd insisted on keeping the school functioning.
