What happened to Rina Trenholm on FBI season 4 episode 11?

As the episode opens, assistant special agent Jubal Valentine, played by Jeremy Sisto, is stopping by the hospital.

Rina Trenholm has been holed up there since her attempted assassination two episodes earlier. During the rest of her team’s investigation into who was behind the attack, Rina suffers a brain haemorrhage; now, Valentine discovers, she’s reached the end.

When he arrives at the hospital, he finds Rina’s room empty. Patient affairs coordinator Susan Blanchard reveals that her parents, who had power of attorney, made the decision to discontinue life support for Ms Trenholm “last night”.

How did Rina Trenholm die?

“It was a decision they made after a consultation with our medical staff and deep reflection,” she says.

Valentine protests, saying he’d spoken to her doctor who had told him it “wasn’t gonna happen until the end of the week”.

Later in the episode, Rina Trenholm’s mother says, “her father and I knew that that’s what she would’ve wanted, so there was no point delaying it”. She also reveals to Valentine that he was the reason she took up her job.

“She was happy in Newark. But she wanted to be near you.”

But how did Rina Trenholm die? As for who orchestrated the attack on Trenholm, the light of Valentine’s investigation falls on Antonio Vargas (David Zayas).

Munroe also writes and plays music, speaks English and French fluently, and identifies as queer

“I am a queer woman and a new filmmaker with two films in development,” she wrote in The Toronto Star in February last year. “I’ve been a professional actor for two decades, and this shift to making my own films is thrilling. 

“But, making movies is hard. And for me, the abundance of recent straight-made and male-made movies about lesbians makes it harder.”
