"Will be returned to you. A courier will bring them by. He won't be armed, so don't kill him."
HUNK had given only as much information as he knew would keep Wesker paranoid enough from feeling comfortable.
When he had briefed Spencer about his plan of attack, he had accepted and approved of it as he normally did. If it had been an inadvertent bonus for whatever plans Spencer had, then so be it. Any ulterior motives beyond the one to accomplish his mission had been dim and uncertain terrain, one HUNK hadn't decided to venture into. If you asked too many questions, you would get your prodding nose slapped.
"All contact off the island from this point onward will be impossible." It was better to tell him now than waste both parties time fencing in the dark. Of course, HUNK didn't specify it was only impossible using any equipment that came off the island, or that only short range frequencies would work, unless you were using pre-checked Umbrella designated frequencies for longer transmissions. And then there were security measures that would keep hijackers off the waves. At least that would keep him guessing.
