Jessica shows her two pair of black leather gloves to Natasha. She doesn't know that they appertained to a mad woman who bewitched them. People who wear them, become mad too.
Jessica grabs Natasha, handgagging and handsmothering her with both pairs of gloves. She holds her breath for long time.
Near the end of clip, Jessica strangles Natasha with both gloved hands until she dies.
