>>103278707It's because we don't know the entire story.
Who made the first move? Did the other party easily agreed? Why did they agree?
It could be that Sirena is a whore, Dean is a faggot, they just did it and Hank is innocent.
Maybe Hank and Sirena's relationship has been shitty for a while, Hank never wanted to talk about it or solve it and Sirena got sick of his shit.
Maybe there was a retarded super science accident that made everyone horny and they couldn't control themselves.
And many other situations. As long as they don't show what happened, people will come up with theories and each theory makes them more or less guilty.
