Ok Steven. New hypothetical.

Manly Piper 54321 calls approach from the ground desiring to
enter Class C airspace after takeoff. Ralph at approach says
"Piper 54321after takeoff remain clear of the class C" Ralph
then goes off shift.

Manly Piper takes off and begins to maneuver around the class
C. He calls approach, and George annswers "Piper 54321 say
direction of flight"

Is Manly Piper permitted to enter the class C?


No.



What bearing toes Ralphs instruction have?


It isn't Ralph's instruction personally, it's approach's instruction. It
remains in effect until an instruction is issued that permits entry to Class
C airspace.



What bearing does George's instruction have?


George didn't issue an instruction.



Does the Manly Piper need to know whether it's Ralph or George?


No.



Does George need to know that Ralph told the Manly Piper to
stay clear, or does George get to start with a clean slate and
make his own evaluation?


George need to know that Ralph told the Piper to stay clear, it would have
been part of the relief briefing.
