Mortality [Wattys2017]

[COMPLETE]
Jacey and her brother Jason were raised by their drug abusing mother and criminal father until the age of eight. Their father was imprisoned and their mother overdosed, causing her own death.
Jacey and Jason then ran away, finding themselves homeless and on the run constantly in the dark streets of Crime Alley in Gotham. They stole and conned their way through life for two years, pawning things off for money. One night they spotted the car of Batman himself. The vigilante was nowhere in sight, so they tried to steal the tires from it. The twins were caught in the process, forcibly explaining that they had no home and no parents.
The Bat saw something, a fighting spark, but also a potentially dangerous criminal future in them and took them in. Bruce Wayne saw to it that the Todds were placed in a school for troubled youths which turned out to be Ma Gunn's School for Crime.
Jason and Jacey earned the Robin mantle a short while later by helping Batman apprehend the gang of thieves. However, they did not wear the Robin costume until they underwent six months of intense training. From there Jason and Jacey took turns being Robin each night for four years.

And that, is where their story begins...
