This little story follows Don't Drink the Koolaid. Duo was injured badly protecting Heero's twin sister... that he didn't know he had... he prevented a civil war too... but he got hurt pretty badly. In this story, Heero is a medical student who is totally willing to use cutting edge medicine on Duo to heal him. Duo... is Duo and a confused and hallucinating Duo... probably not as helpful.
