You, Percy, and Grover were on a quest.

The three of you had just barely escaped Echidna and her lovely(disgusting) pet poodle-turned-Chimera, and were continuing on your way. As the group made their way to a nearby hotel, using some of Grover's spare mortal change, you noticed something.

Percy looked sick.

Sure, he had tackled you out of the way of getting hit by the Chimera's poison. But why did he look so bad? His cheeks were sunken, the bags around his eyes darkening as the day progressed and night fell. His breathing gradually became more shallow, and it seemed like he wanted to lean on you for support.

So when you all arrived in the hotel room for the night, Percy slumped against the doorway. Usually, he would make some sly joke about the less-than-great accommodations, but he looked tired.
