Here is the ultimate Justin fic:

Little Amish Justin, who has undiagnosed Tourette's Syndrome,
runs away from home because he's become a cutter. At summer
band camp he meets Brian, a tall and handsome priest who is
also a detective AND a vampire. They fall in love, but Justin
starts having seizures, as well as an eating disorder, which
is made worse by his lactose intolerance and inability to
process glutens. Justin runs away and becomes a hustler in
New Orleans. He's arrested and released to a psychopathic
couple, Mikey and Ethan, who lock him in a cellar. Meanwhile,
Brian goes blind and gets cancer. When his guidedog is run
over by a bus, he wanders around, groping, until he hears
his "Sunshine" singing a song by Coldplay/Mariah Carey/Frank
"Sumatra." He follows the sound, which is coming from that
cellar. He butts his head against the wall and it falls,
releasing Justin from his prison. The blow to the head miraculously
restores Brian's sight! Just then the Pope appears and tells
them that gay priests can now marry and that the Amish are
now considered Catholics! Brian uses his detective/vampire
powers to track down the Evil Mikey and Ethan, who turn over
a new leaf and open a bed and breakfast together. Justin's
father sees the light and invites Brian and Justin to live
at their Amish farm, Britin, except with electricity and a
hot tub and very large four-poster bed. Justin realizes that
he's pregnant and gives birth immediately to quadruplets
named Brian, Jr., Justin, Jr., Briana, and Justine. And
Justin's gluten problem is helped by a change in diet.

And they all lived happily ever after!
