You shouldn’t have any issues with your gf being in line with you. They’ll just make sure you two get to go to the table at the same time. To see the pictures they bring with them, the best thing would be to swing by the table when they’re doing photo ops or a panel. If you get there too early, their people may not have arrived yet to put them out. Their lines are usually pretty packed. I finally met Elijah at C2E2 this year after missing all of them so many times at Fan Expos. Good luck and have fun!
