No he's not. He literally had a temper tantrum and made Louis' job harder all because the mc couldn't remember sleeping with him. And he knew who the criminal was all the time, too, *while* he was refusing to help the MC. Felix on the other hand, if it is true he doesn't know Benjamin is his, doesn't deliberately f*ck someone's life up. And clearly in Felix' world beta males cannot have children and just as clearly Felix hates omegas. Even if he wouldn't deliberately f*ck up that mc's life if and/or when he knows he's an omega, that's still not a reason why he would even want to *think* of Benjamin as his since it would make the MC an omega.
Besides Maetel was sober yet he didn't know he was the father of the baby nor that Louis was drugged when they slept together, until the rope man told him about the drug he'd given our MC. For one if he didn't know that Louis was drugged why would he think that a normally upright man would so easily jump from his bed to another's like there was no tomorrow. For two the fact he didn't know Louis was drugged is just as odd when Louis' behavior when they were together that night was obviously not that of a clearheaded person. And Maetel has NO reason to convince himself otherwise like Felix does. For three, Maetel doesn't have the same kinds of prejudices as Felix which should have made it even EASIER for him to figure out he was the father.
Smarter than Felix? Yeah right.

One thing for sure is Maetel’s definitely smarter than Felix.
