Derek stops short the moment his eyes fall on the huddled mass in the corner. The beta lying crumpled there is trying desperately to make himself seem as small as possible and cover his most vulnerable areas. It takes Derek almost a full minute to realize who it is and another to realize that he’s wearing tattered, blood-stained remains of the clothes he disappeared in over four months ago. The acrid stench clinging to him tells such a vivid story of the atrocities he must have endured while he’s been missing that Derek thinks he might be sick.
“Stiles?” he asks in disbelief.
