Nice clean accident

I played a lot of video games with my friend Jamie.
He was supposed to be doing homework while undergoing dialysis treatments, but who would dare give a sick kid an F?
I was enough of a tissue match, and I gladly gave up one of mine.
And things were great. Best friends forever.
Until I got sick.
Kidney disease.
Which means Jamie’s also doomed.
We did some research, hacked some medical records.
Found a guy nearby who’s a match. And healthy, too.
We’ll break into his garage, cut his motorcycle’s brake lines, and hope for a nice, clean accident.
