I'm not sure I understand your concern.
Ever since your engagement ended,
I've witnessed some disturbing changes
in Daniel's behavior.
He's become petulant and angry.
I'm sorry to hear that.
I knew you would be.
Unfortunately, my son
has walled himself off from me completely,
but I believe that you still have the power to reach him.
And what makes you think that?
Because in spite of my interference
and your transgression last winter,
I'm of the opinion that my son is very much in love with you.
And assuming that you ever loved him, too,
I'm asking you to step in
and help stem the tide before it's too late.
Unless of course your feelings for him
were less than genuine all along.
Of course not.
I loved him very much.
Then remind him of the man
that he aspired to be when he was with you.
Persuade him to drop his interest in Grayson Global,
and I will stand behind you every step of the way,
come what may.
