Alex knew that if it wasn't for Luke's angry outburst the crowd would have cheered and ridiculed him. No one did that now, maybe that was why Lily didn't seem pleased as she saw him, except for the fact that he could probably kill them. She was scared of him, everyone was.
Looking at him, Alex too felt the same. That madness in his eyes. It reminded him of moments he had buried deep inside his head. Moments of hateful looks before he got beaten up almost unconscious by his father. Those moments were taking shape in Luke's eyes right then and there while he was shivering and waiting.
