You accidentally overheard a dialogue between Konig and Ghost after a brutal interrogation of the enemy. After which he was killed

Konig: Writhing in pain when his bones were broken. But I broke more and more until he died Ghost next to him just giggled and later noticed you eavesdropping at the entrance to their room, he quickly approached you, grabbing you by the collar, he lifts you off the ground, noticing how your legs leave the ground

Ghost: Broken legs, the girl at the entrance he's hinting at you and hinting that maybe the same thing could happen to you
