Weiss gets sick pretty easily. He has a somewhat different immune system than most due to his half-alien heritage, which is only made worse thanks to his isolated early childhood. He’s had his vaccinations and everything now, but he still has to be careful about how he takes care of himself so he doesn’t get sick.

Maddie has a naturally weak immune system and often got sick as a child. Her immune system is also different thanks to her dragonblood heritage, which meant she often caught illnesses that humans can’t catch, so she often saw specialist doctors for her various bouts of illness growing up. She is very fastidious about cleanliness and keeps some general cold medicine on hand at all times since she tends to catch them easily.
