CLEVELAND -- "I really don't like the color pink," Michelle Knight said on Sunday night's edition of "Dateline" on NBC while looking at a model of the home she was held captive for more than a decade.

It was in that pink room where she says the "torture began."

During the conversation with NBC's Savannah Guthrie, Knight also explained how Ariel Castro put poles inside the pink room so he could tie her up.

"When I was untied, my arms, my legs, I couldn't walk."

Then, while pointing at the staircase of the model home, Knight showed how Castro would drag her down to the basement by her feet. She said her head would hit the stairs as he dragged her along.

Another element of those stairs, according to Knight, is that Castro would block access to the other floors of the home by filling the staircase with various things like pieces of furniture.

"He thought the whole thing that he was doing was normal," she says.

As for Castro's room, she says that they called it the "cubby hole."

Tuesday marks one year since Knight, Gina DeJesus and Amanda Berry escaped the Seymour Avenue home.

On Friday's edition of the TODAY show, Knight revealed she was changing her name to Lillian Rose Lee. She will be in New York City on Monday's edition of TODAY.

Knight is reportedly taking cooking classes with aspirations of becoming a chef.
