Aldrich has a worried look on his face as he stares at the closed door where Luc and Brina left. He knows that Briony is not fully in control of her supernatural senses. What happened last night was proof of that.
If it was up to him, he would not want Briony to do that again. Though sensory overload was not a serious problem, Aldrich cannot help but worry whenever Briony is having discomfort. Last night was the worst to the point that she lost consciousness.
Aldrich was so worried about Briony that he barely slept that night as he was watching over her. Once in a while, Briony would whimper and flinch in her sleep. Aldrich would be instantly beside her to comfort her in her sleep.
Briony was just there in his reach. He could have laid down beside her and gathered her in his arms, but Aldrich knew that it was not right. At least not yet. So he just settled on sitting in Brina's bed and watching over Briony while she slept.
