Telepathy. The ability to hear the thoughts of others and pry into other minds. Suddenly, you have it. Or maybe you always had it.
And now you're connected, for better or worse, to another person, for who knows how long. You can feel their thoughts and, more alarmingly, they can hear yours. You share dreams, you can feel them there constantly, you their joy and their grief.
( You and I share a profound bond. )
