I think that there are some basic elements that can be explored. The most elemental would be how the heroes are on a journey where peril and challenge are evident every step of the way. The idea of both heroes not being able to have a simple and easy time of it might be one area of comparison. Perhaps, discussing what they encounter along the way and how it is similar might be another point to explore. Additionally, I would suggest that, in the end, both heroes wish to go back home and will fight and persevere through this end. The assistance they receive from "other worldly" figures might be another point of comparison. Their own sensibilities that are well honed could only get them so far. The assistance of outside forces are critically important in assisting them in their respective quests.
