Once upon a time, you were sick. You were all sick, though maybe you didn't know each other [well] enough to have cared or offered any sympathy between you. Maybe you were so wrapped up in your own problems that you couldn't come out of your shell enough at the time to care about anything other than yourself - sickness has a way of making some people a little bit selfish.
Then he appeared - the doctor - and he promised it could all be made better if you tried his experimental and unsanctioned surgery. No taking pills that made living hell, no chemo that would render your body weak for months, no being bedridden or worrying your parent(s) or missing out on precious school or work. One night and you'd be back on your feet healthy as an ox or your money back, guaranteed. He even signed a contract to that effect... He was a weirdo, liked to wear this strange bird mask, and it should have been too good to be true but you were desperate at the time. Sickness can do that to people.
It's been awhile and somehow you've convinced yourself it isn't your problem - it isn't real, it isn't something you can handle, it's too dangerous. Against all odds you've sat in on a support group with a handful of folks who have the same connection to the Doctor that you do... That little dot scar on your head where he trepanned you without explaining that was what would happen.
This time, when the lights go out the monsters will show you how real they are.
