> For instance, Littlefinger started out seemingly as a small player but then we learn later he was actually a rather significant player in almost all aspects of what has been happening so far. Granted his obvious interactions are with rather important people but by appearances the number of interactions seem low while actually being quite large. i would argue that that makes him a significant plot device, rather than a significant character. tyrion is a major character not because he influences events the most, but because a lot of the book focuses on how events relate to him and vice versa.
