I'm sorry, do you have more information than the rest of us? Has there been some meet and greet with Drew that I missed? Why is it there's a shitton of people who are saying "oh, I think Drew will turn around and become one of the good guys"?
Every bit of information, either from Hunter, or dad's journal, tells us Drew is on the side of Hunter, and is even worse than Hunter himself! Drew doesn't need chemicals to get women into bed. They're charismatic enough on their own. People trust them because they appear a woman and then Drew fucks them over, and you're fucking falling in their trap! Hunter told you their MO and you just walk right into it anyway!
Drew is the Prince of Seduction. Drew has no feelings for his sister and nieces. They're just holes to fuck and then move on.
