Disclaimer: Don't own Star Trek; not sure who does other than it's not me. And, unfortunately, I cannot and do not profit from this work of fanfic.

Beta: Ceri – a million thanks for her patience and wonderful ideas

Author's Notes: This is a follow-on to my story Complications. Reading it first will help but isn't necessary. This is a McCoy-focused story – if you don't like the character, you probably won't like this story. That means there's also a lot of medicine – some of it graphic, very little (if any) gore.

Prologue – CMO 101

"I know all of you think there's a need for this class." Admiral Elise Waylan, Surgeon General of Starfleet, gave the assembled students a tight smile. "There's not. You already know what you need to know – you just don't know it yet."

McCoy exchanged a sly glance with the two men and two women who made up the class – all newly minted starship CMOs. They all looked as clueless as he did. The five of them were seated in Dr. Waylan's office, the same office in which a week ago he'd been given –maybe ordered to take was more accurate – the position of CMO of the Enterprise.

"Look folks. At the end of the day, you're physicians and you already know how to practice medicine – I hope. The biggest difference between being ' just' a doctor aboard a starship and being the CMO is that it now all rests with you -- the decisions, the responsibility, the authority are all yours. Yes, you can contact Starfleet Medical or the nearest Starfleet medical facility. But I can promise you that 98% of the time, we're going to support your decision – because you're there. You're the one who knows the people and issues involved. And, if I didn't explicitly trust your judgment, you wouldn't be sitting here right now.

"So, put down your PADDs. Seriously. This is about listening and thinking – not taking notes. Reflect. Consider. Analyze. Question. I've got less than three days to turn you into CMOs. So let's get started."
