When John finds out Sherlock is ill, he has to make sure. Really, absolutely sure. And for a while, it's okay, because medicine has advanced to the point where Sherlock isn't going to die any time soon. But when Sherlock takes a sharp downward turn, he asks John to do one last thing for him. FEELS ABOUND. Not using warnings because spoilers, but there are some. 32 chapters.

After the night John was having, it was too much to ask of him to lie dying on a dirty kerb staring up at Anderson and Donovan. (answer to prompt 13 from 2013's Watson's Woes July challenge.)

Johnlock. Teen!lock. Sherlock attempts to commit suicide. He almost succeeds.

Sherlock finds himself in the difficult position of admitting his feelings to John Watson after The Fall. While he is quite sure that there is no one else but John, fate doesn't seem to agree. Shameless Johnlock implications, Sherlock POV.

Sherlock is diagnosed with a terminal illness. Warning: angst like whoa.
