"Christ, look what I've done to you..." Lifting a hand, John brushed his fingers along the deep marks with the upmost care, the frown lines in his forehead and around his mouth growing deeper as the concern banished his darker thoughts. "See what I mean? This is not good, Sherlock. I've really hurt you."
