He is one of Morgan Everett's only means of physically communicating with the outside world, as he is bound to his home at all times, due to Majestic 12's control over Paris. Toby will meet JC at a metro station near the Cathedrale de Payens, where he will knock JC unconscious and wake him in Everett's top-secret home. He does not appear again after this. If Jock is killed in Area 51 by the bomb the fake mechanic put in his helicopter, then Everett consoles JC by telling him that he has ordered Atanwe to kill the mechanic.
He can be killed by JC in Everett's residence.
