Jonathan Price

"Though inordinately young for such a role, both MI-6 and SAS have ensured us that he is a veritable prodigy and will not fail to meet the objectives of this mission."

- Ryan Jackson describing Jonathan

Jonathan is the name of a British Special Air Service (SAS) operator assigned to Operation: Charybdis alongside Ryan Jackson.

This could concievably be none other than Captain Price, since they both have the same first name, and are (were) members of the SAS.
