This first story in my new "To Hell and Back" series takes place shortly before Spock departs from the Enterprise to undertake the Kolinahr discipline. It has no connection to my other series.

Coming off a difficult mission, the men find a new member of the crew distracting. It's a good thing that the feathered Avitian is under Spock's tutelage. Or is it?

The replicate Tobias has died, and now Spock's inexplicable behavior has even Dr. McCoy looking toward Vulcan for medical assistance.
