Technically Sophia is the victim of "Extortion", and not "Blackmail". Aren't they the same thing? No, they are very similar.
Blackmail: the action, treated as a criminal offense, of demanding payment or another benefit from someone in return for not revealing compromising or damaging information about them.
Extortion: the practice of obtaining something, especially money, through force or threats.
What would an example of Blackmail on Sophia be?
Sophia goes out on a 2nd date with the fratboys on this coming Friday. Neil the neighbor (the one who got slapped for drugging her, and trying to take advantage in her bathroom) was in an argument with his wife Amber, and went out to have a drink that same night to blow off some steam. Coincidentally Neil spots Sophia at the nightclub. She does not see him, and he keeps his distance from her. Neil notices she is there with a man that is NOT her husband. Neil gets out his cellphone and subtly records Sophia sucking a fratboys cock in a backroom.
The following morning "knock knock knock" on Sophia's door. Neil is there. She says, "What do you want?" He says, "We need to talk, I saw you at the club last night." She invites him to the backyard to talk about it out of earshot from her family. Neil holds up his phone and shows footage of her sucking a fratboys cock. Neil says, "This isn't right, and your husband is my best friend. If you don't tell him I will." Sophia says, "Please don't, I'll do anything, do you want money, it would destroy my family."
Neil offers to keep her secret in exchange for a weekly blowjob. That's blackmail.
On the other hand, Aiden is not of yet blackmailing Sophia. Aiden has basically said, I'm going to be kicking your sons ass, me and my gang. I don't care if you tell your husband. I don't care if you tell the police. I don't care if you tell the principal. My uncle is the best lawyer in the world and has got my back. Come to school with no bra on tomorrow or I'm going to beat your sons ass some more. This is Extortion, and not blackmail.
Blackmail is a specific subset of extortion. Aiden may blackmail Sophia in the future, but he is currently extorting her. If Aiden gets Sophia to do something on camera, then threatens to share that with her husband ect in the future, his extortion bleeds over into blackmail territory.
Hope this cleared things up for folks.
