I think we alreayd know the answer to that. Diane doesn't do thinking, she merely an empty vessel that regurgitates Catholic dogma no matter how nonsensical.
"It would be up to the complainer to establish some logical connection between what God knows what will happen and the mind of the one who makes a choice so that the mind of the person making the choice no longer is making a choice. It seems that the critics are saying that the choice-maker is affected by God's knowledge to such an extent that his freedom is lost. If that is the case, then can they prove this logically?"
Yes we can.
