Character A - Tumblr Posts

C is just as exhausted as A is and they're acting like that because they're too stubborn to admit how unwell they feel.
Character A is stuck with C, who is not their usual caretaker (Perhaps Caretaker B is away on business) when they get sick. They can already tell it’s going to be a pretty bad time, but C is less than sympathetic. “You’ll be fine, just take a nap and a Dayquil and tough it out! We’ve got work to do! Stop whining!”
Eventually A stops mentioning how awful they feel. C assumes that means they’re getting better, if they’re not bringing it up. Until they find A passed out on the bathroom floor, boiling hot from their fever.
(Bonus points if B finds out what happened and rushes home early – not just to nurse A back to health, but to rip the repentant C a new one.)
Character A: randomly losing control of their magic and instead of finding an outlet to release it on they just let it flow over themselves, use to the pain
Character B: Noticing one night, suddenly very mad at Character A

This kinda thing cracks me up
