[quote]On the night of her murder, Vanessa had unknowingly used her abilities to activate a Hyper-Gene in each of her friends who had been attending her birthday party, including her brother, that night. These teenagers would come together to solve Vanessa's murder and attracted the attention of Dr. Jonas Lehrer and Special Agent Yakob Kowalski.[/quote]

Cliff-notes:
[list]
[*] Attended Vanessa Bordeaux's birthday party; unwittingly was subjected to virumosis via Vanessa's own hyper-human ability. 
[*] Jonas inserted himself as a new teacher at Mather Memorial High in Crestwood Hollow, while Yakob worked behind the scenes using the resources of the fledging H.E.L.P. organisation as much as he could to help them.
[*] Autumn Miracle began stalking the hyper-humans inadvertently created by Vanessa, killing and dismembering them to understand their, and her own, new biology. She killed 5 students, before attempting to kill Summer Carlyle and being stopped by Aiden Roth and Viktor Bordeaux's timely intervention.
[*] Autumn was outed by Aiden and Viktor, and the ensuing events outed Jonas' study group for the Hyper-humans they had become to the public. H.E.L.P. and 3HA were forced to step in, arresting Autumn - though not without incident, which left Yakob wounded and Autumn herself comatose in H.E.L.P. custody.
[*] Unable to return to Mather Memorial, Jonas and Yakob founded PRCU for the 8 remaining study group members, and the rest is history.
