C - 'try' to succeed. She's clearly a type A individual looking at her own abuses of power, it would be a dramatic character shift for her to just give it away.
Claire hasn't been regressed yet because it needs the manager's signature, but Mark is the only one who seems to know and has locked away the form. Seems to me that a regressed Mark would eliminate the threat and a pissed off Claire could force Alea to fail.
Although.... hypothetically, what would happen to a submissive baby girl if her mommy were to be forced into regression?
