He didn't like how this whole scene was playing out. Not one bit. He's seen this before -- from another perspective.

Law is caught up in a scuffle with the marines on a snowy island His crew is scattered, fighting, but he's not worried about that. The Heart Pirates are capable.

What's worrying is your absence. You, his 12 year old child, who'd been sick, were no longer in the little shack where he'd hid you prior to the fighting. He's following the little footsteps in the snow you'd left behind.

Why had you run away? Why hadn't you stayed in the shack? You had always listened to him, what happened? Had someone gotten to you?

As said before, he doesn't like this one bit. It reminds him too much of the night he'd lost Corazon.
