Sunny what im thinking is that the TAOH that Aragorn/James read in his universe is not the exact same TAOH that is in.. well, TAOH. The characters are the same and have experienced similar things, but not the exact same. So Aragorn would be a bit shocked that these characters showed up, but when he tries asking them if theyve done things theyve never done, theyll be like "uhh, what?" Think of it like actors in a movie. They represent a character in a movie but they do not have the same memories or experiences, because theyre just actors. The TAOH cast are like actors, because the TAOH that Aragorn read is a twisted version that was twisted for more drama or action you could say.
