Hermione might use her extensive knowledge of magic to try to understand the portal, while Ron provides support and comic relief in the tense situation.

One interesting plot point is the combination of magic and survival skills. For example, in some fanfics, wizards have to use spells to hunt or defend themselves in the Hunger Games - like setting.
