Mr. Wilson had narrated a different plan to the CEO of Starlight. They planned to send Janet away in the name of medical care. When the time comes or if the truth comes out, they would hold a simple press conference and announce that Janet was the mother and she had fallen ill unable to bear whatever Gianna did to Alvin's son.
They were going to make Gianna into a villain and Janet into a victim by pretending like Janet had a good relationship with Alvin. The medical reason suppresses other rumors. The CEO had given in, believing Alvin wouldn't be wasting time announcing his relationship with Janet.
However, the plan Wilson narrated to Janet was entirely different. He let her know they were going to victimize her which will gain her sympathy and publicity. Then they would bring in lies to negate the effect of the truth.
