X-Ray Vision and Invisibility: See through anything but lead, to any degree, at any place, at any time. So yes, you can go to sleep and you won't be looking at your brain. You can also become invisible to the naked eye, at any place, at any time. As you become invisible, so will anything you touch. This is for life. You have complete control over these powers.
Emma Watson: She will be your girlfriend, loyal, trustworthy and faithful. If you mess up by lying, being unfaithful or if she feels unappreciated, she'll dump you right then and there, grieve for a day and move on. You'll lose all contact with her if you screw up. You only get one chance here. This can potentially be for life, unless you blow your chance.
