K-Unit's Reentry

What if Snake was John Watson? (I know Snake was a red head and from Scotland, but still, what if) Alex returns to MI6 after 5 or so years (his choice). Mrs. Jones, not feeling comfortable in using him again signs him for a 3-5 yr contract and regroups K-Units as his extraction team. Rated T. Also, I'm new at this. Not beta'd (I think that's the term...not sure?)
