Katerina is stuck and she knows it. He did a good job with the chains - too good of a job. The chain wrapping unforgivingly around her elbows - pulling them tight until they touched - and her wrists. Plus a chain frogtie. And not even able to move around too much, maybe to get to the door; she was chained to the bondage pole, her own body weight on the poole platform keeping her in place
And that nasty, sticky ducttape gag - she can't even cry for help, call to be rescued. All she can do is making those damsel in noises!
