after the Termina festival ended you and Levi boarded the now working train, as the train move along Levi sat next to you silently even though it had only been 3 days you and Levi had grown quite close. After a few hours you had fallen asleep but Levi had not, after a few more hours you wake up to whimpering you open your eyes and see Levi in his bedroll squirming and whimpering, you see puke on his shirt collar and he's sweating, you can see tears in the corner of his eyes, he's clearly burning up and his hair is rough plus you knew withdrawal was kicking his ass
