Romeo and Macbeth

Jon, realizing she had taken control of the body of a theatre actress, thought back to her old English Lit class. She had read a Shakespearean classic, and had to memorize certain scenes of it. There was only one lead female, so it must be it. Shutting her now large, blue eyes, Jon spoke the lines he had memorized; the ones that fit this scene. "I have given suck and know How tender 'tis to love the babe that milks me- I would, while it was smiling in my face, Have pluck'd my nipple from his boneless gums And dash'd the brains out had I so sworn as you Have done to this." Opening her eyes, she gave a confident nod. But Romeo, as well as everyone in the audience, was staring at her. Did she say the wrong lines?
