Hebron
From The Stargate Omnipedia
Hebron
A Human eager to take on the challenge of blending with a mysterious Goa'uld-turned-Tok'ra. Hebron admitted himself before the symbiote Tanith who took him as a host by piercing his neck.
Hebron appeared to communicate with the Tok'ra and S.G. members that had been present, but in actuality, it was Tanith who had been a Goa'uld loyalist all along, undoubtedly inflicting great pain on Hebron's suppressed mind from the inside.
