Poor 13D. His wig alone would have made him stand out. A full head of hair that was clearly not his original color perched atop a hairless , browless head. But his tenuous grasp on reality made him stand out far more. He appeared in the galley telling a crew member people were attacking him and he wanted to file lawsuits. Then disappeared. Then reappeared with a 'limp' arm saying one of the crew had shoved him to the ground. Then nearly pulled the lavatory door off the hinges trying to push a pull door.
I was sent to deal with him (there was only 1 passenger in First Class, I wasn't busy) and try to assess his level of crazy. Not that I have any training in this, was just the only one not tired of him by then. Tried to get him to sit down with the offer of a drink. He said 'they' were watching his seat. So offered to move him to an empty area of business class, and have a cup of coffee or tea. He didn't know 'who he could trust'. So offered him a sealed bottle of water and/or a closed can of soda. Explained he was suing everyone on the plane. When I got him to sit, he kept his tray table at a 90 degree angle to keep the Nazis away. Think of how soon WWII could have ended, if that was all it took !
He could not determine if he had a green card or not, for the immigration paperwork. Explained he was going to Reno for a conference ( dying to know for what). When last we left him, he was scratching his head over the address he was headed to. I hope some family met him wherever he was going, and man, did my post flight happy hour mojito go down a treat after this flight. I need a rest!!
