I believe it makes mention of the UNSC trying to abduct Jan (Spartan 1.1) for the Spartan-II program, but her father James (Spartan-I) killed the would-be kidnappers. He said she could do hop scotch on her hands (rather than feet), and that was what had attracted the recruiters, and as such she "killed at hopscotch". This is from ilovebees, which is embraced as canon by Bungie.
As such, it is a possibility John was a Spartan 1.1, but the likely hood is that the Spartan-Is wouldn't be duped the way normal people were, and the UNSC would have been short a candidate and several people if John had been a 1.1
I like pi.
