He was really friendly when we met him on Friday. I had a 'Bending the Rules' poster for him te sign (a movie with him & Edge). He was looking at it and then said 'I don't remember my character's name in this'. I had to tell him I also didn't remember, because it had been a while since I had seen it (the Edge character was named Blades, that I remembered). I told him he could write that on the poster, that he didn't remember, so he did. After he signed it, he said Edge would definitely know both character's names.
So on Saturday, I had the poster signed by Edge & told him the story. He had to laugh & he indeed remembered both character's names: Blades & Gold. So near the end on Saturday, when nobody was queueing at Jamie's table, I went over, showed the poster again & asked him if he remembered signing it. 'Of course' he said. I then told him his character's name was Gold. He then said 'what was my character's name, Goat??'! I I replied, no GOLD!'. He replied 'Aaah, right, Goooold! Cool man, thanks for letting me know!'.
So fun guy & nice meeting him!
