He knows cats do it. Crawl off into some dark corner and let themselves deteriorate rather than admit that they're hurt. For the longest time, he'd thought they were stupid. He knew they did it to avoid the predatory jaws of bigger animals even if they knew damn well no such other animals were in the vicinity. A house cat held this kinship with it's wild bretherin. Better to die alone than risk getting hurt again.
But you're sitting there in your room, face contorted in anguish as you clasp the stained cloth down on your wound. It could be a gash, gourge, slash or another type he doesn't know. He can't be sure, but he knows you're in pain considering the tear tracks that litter your face, salty soldiers clearing a path through the dirt and muck that had accrued on your face during your prior mission.
He's always considered you his to some extent. Since he first saw your wide-eyes glancing around the manor, he's wanted nothing more than to scoop you up into his arms, to keep you safe from whatever dangers might otherwise rear their ugly head your way. Logan had gone through a phase of saying Warren had become your "mama bird", muttered and chuckled under his breath as though Warren might contest the claim.

Whatever your reason may be, Warren's heart twists in anxious knots as he watches you stare up at him.
