Hear me out, and you probably heard this one a lot already, but
Sick Whumpee who barely made it further than the bathroom in days. The rest of time is spent in bed, shivering despite the heap of blankets they have gathered on top of them. They tumble between sleep and consciousness, unable to find proper rest, and yet not managing to stay awake for longer periods at a time.
Caretaker, who at first thought Whumpee was being dramatic and waved their behaviour off, is quickly taught different as when they call Whumpee to eat, they don’t appear. They go check on them, and find them on the floor, slumped against the wall, the closest place they could reach after their legs gave in when they got up to meet Caretaker downstairs. They lean down to whumpee, and their stern, almost annoyed expression drops at once as they feel the heat radiating from them without even touching them yet. They lay their hand on Whumpee’s forehead, almost immediately backing away, their worry increasing when Whumpee holds their hand close because it’s so nice and cool…
Caretaker picking Whumpee up with ease, did they eat anything at all? And placing them back down in bed, only earning a tired groan from Whumpee as they can finally bury themselves under the blankets again. Just a few minutes later, when Caretaker returns with a warm cup of tea for whumpee and something to birng their feaver down, they find them sleeping once again.
Caretaker - feeling bad for being so harsh at first - now refuses to leave Whumpee’s side. They cradle them to their chest when they’re shaken by another feverdream, softly rocking them as they weakly cling onto their shirt. Every now and then they brush a sweat matted streak of hair from their forehead, and press a small kiss on their head, whispering that they will get better, that they won’t leave their side, They use the bits of time where Whumpee is actually awake to have them drink, and if it’s just a sip before they go back to sleep, then that’s fine, just have something please
And every now and then, Caretakers tired eyes close as well, though it barely ever lasts more than a few mere moments before the rattling breath and the delirious whimpers of Whumpee let them snap back to reality again, back to the shivering, suddenly so…small form still laying in their arms, taking up all their attention at that very moment. They can rest when Whumpee is fine again, after all.
