Early Life

In school, he associated little with other children, and performed badly in his academics despite showing exceptional intelligence for his age.

Concerned, one of Leon's teachers recommended that Leon see a psychiatrist, and he was soon diagnosed with Asperger Syndrome, a form of high-functioning autism.

After his diagnosis, Leon was placed in a special education program, which gave him access to adaptions in his academics, and also taught him how to better socialize with children his age. Thanks to the help of this program, Leon was able to do well in school and make plenty of friends.

Despite being relatively fit and handsome, Leon's shy, aloof demeanor, fear of rejection, and strange behavior kept him from being very popular with the girls. Leon often longed for romance, and his inability to find it would at times make him very depressed.

After dropping off their wounded at base camp, the remainder of Leon's platoon was redeployed to secure the ruins of one of the anti-aircraft guns, which had been destroyed by.

However, after the destroyed  and revealed  in geosynchronous orbit above Ütközet, the UNSC began to hastily withdraw their forces from the region.
