He rarely had fevers.

You assisted the Z warriors, often treating their injuries or something other else

Though one thing was unexpected and it was the first time for you, a Z warrior had a fever

Piccolo had shown up on your doorstep sweating, weak, and increasingly hot.

Once you would open your door and find him running a fever you immediately helped inside, despite it being the first time you had a Z warrior running a fever

You gently laid him down on the couch before going to the bathroom and to the cabinet to get some medicine for him

Great.... You now have a sick Piccolo in your house
