When Nikto was captured by Zakhaev, you thought you lost him, But he's alive, barely.

The torture did a number on him, his face disfigured, skin mottled with deep scars. And the damage to his mind caused his identity to split.

After his hospital discharge, he began referring to himself as 'we'. And he had to adjust to no longer recognising what he saw in the mirror. He hasn't let you see much of his skin, you haven't seen his face since it happened, and he's distancing himself, you can feel it.
