Rain: panics at first but will give you medicine and make sure you are comfortable at all times.
Sodo: calls you a baby at first (as a joke) but is panicking on the inside. Like rain he will make sure you're ok and bring you snacks.
Swiss: goes to cardinal in a over the top panicked state because he thought you were dying. But once he finds out you'll be ok eventually he calms down some.
Mountain: brings you tea and medicine. He won't let you out of bed and if you really need to get out of bed he'll carry you around.
Aether: knows exactly how to deal with the sickness and will try and use his healing on you. Babies you until you feel better.
