Task: Question Answering
Input (English): Passage: New Orleans narcotics detective Anthony Stowe is a heroin addict who is teetering on the edge of oblivion, and he could not care less. At the moment, he is trying to bring down his former partner Gabriel Callahan, who has become a drug kingpin. Callahan is trying to, and slowly succeeding at, taking over the New Orleans underworld.
Stowe botches a sting operation against Callahan, resulting in the death of fellow cop Maria Ronson, whose fiancée, fellow cop Van Huffel, nearly comes to blows with him over it. Chief Mac Baylor has a very blunt chat with Stowe, who is dismissive. Stowe is approached by fellow cop Walter Curry to help his nephew beat a drug-dealing charge; he instead turns Curry over to Baylor, who fires him. After barricading himself in the station bathroom, Walter confronts an unrepentant Stowe and condemns him for betraying his fellow officers.
That night Stowe meets with his estranged wife, Valerie, who tells him that she's pregnant, but that he's not the father. Valerie, whose marriage with Stowe is close to collapse, has been seeing a man named Mark Rossini, the gym teacher at the school she is principal of. But he may not be the father either. Stowe brashly accuses Valerie of being impregnated by Callahan, and she tells him she never wants to see him again.
The only thing keeping Stowe from total collapse is his dogged pursuit of Callahan. But he drunkenly stumbles into an ambush masterminded by Callahan, and is shot in the head by Callahan's right-hand man Jimmy. Stowe undergoes emergency surgery, and ends up in a coma. Months later, he recovers to the point that he opens his eyes, and is transported to his and Valerie's house to recover properly. 
Question: Which person is Van Huffel upset with?
Output (English): Anthony Stowe.
