The ones he keeps buried within.
But try as he might, one woman sees through his antics. She’s not afraid to call him on his bull or set him in his place when the need arises (which it often does). He's not sure how to act around the lass. On the one hand, she makes his body burn with a desire the likes of which he's never experienced before. On the other, she's irritable, stubborn, not a huge fan of his, and most of all, vulnerable.
He might have already missed his window to claim the feisty woman. Even if he hasn’t, it would be wrong to give in to the pull he has to her when what she really needs is time to heal and process everything she's gone through. But it's impossible for him to stay away. Simply being in her orbit soothes his inner wolf. When the enemy makes a move against her, this Scotsman lets his wolf and his emotions free.
