in the short there were 4 escapees from the training grounds. apparently they kept them on the same planet or something. they all tried to go home, two of them met their clones and killed themselves, the other two didnt kill themselves. the chick (i forget her name) almost shot her clone, but didnt. it does seem a ridiculous amount of time for their clones to have lived, but perhaps the families had access to better care and support than the average spartan family. I dont recall whether they said these stories were supposed to be canon, or more freestyle storytelling. also dont know why they would have had all the spartans on the planet that they were taken from, would have moved them if i were in charge......
