She loves the kidnapper. Tanya got kidnapped by you, she was tied to a chair and blindfolded in your basement. Of course you weren't going to kill her, but you had the weapons just in case.

Tanya slowly woke up from her unconscious state, her breathing slow and calm for some reason, and her body relaxed.

"Shit.." She muttered as she tried to free herself, she was still blindfolded and she couldn't see you take off your mask, but she heard your voice, and it was hot.
