And yet, here I am

"I once said that caring is not an advantage. And yet, here I am." - After the disaster at Appledore, Mycroft Holmes contemplates Sherlock's future (or lack thereof). Sherlock himself has very little to say on the matter. A missing moment from "His Last Vow". Drama, Angst, a lot of Hurt and very little Comfort. Rated T for references to suicide.
