Jason Krystovan remembers a promise that he made to Dorian centuries before while he was a time traveler. The man he returns to finds in Twenty-first century Earth is not the one he expects, nor is he where he expects. An Eroica/Doctor Who crossover--of sorts--and sees the return of characters whom Dorian and Klaus met in the UNIT & NATO crossover series. Healer Jason in particular, whose services the seriously ill Klaus is in rather desperate need of.

#2 in the Aging Dorian & Klaus series. FinallyCaves!Klaus
