The synopsis of FBI: International season 4 episode 10 reads,
"When a Russian biochemist is assassinated for trying to defect with his highly sensitive biotoxins research, the Fly Team springs into action to protect his daughter, whose father’s last wish was that she get his research to a trusted American microbiologist. Meanwhile, Mitchell (Jesse Lee Soffer) stays behind to help Vo (Vinessa Vidotto) during her recovery, and Booth (Jay Hayden) clashes with Smitty (Eva-Jane Willis) when he finds out she could jeopardize his promotion."
The upcoming episode titled Keep Calm and Deliver the Biotoxin puts Raines at the center of the action, as seen in the promotional video. He is seen carrying a briefcase and trying to protect a young girl while chased by a group of men. At one point, he is heard saying, "If you shoot me and I drop this, it kills us all", and it is safe to assume that he is trying to safely deliver the biochemical weapon elsewhere.
Fans are also interested to see Vo's recovery arc in episode 10, after being fatally shot in the fall finale. In an interview with TV Insider on January 28, 2025, Vinessa Vidotto talked about her character's healing journey. She said,
"I think she’s a pretty resilient, strong woman, and our show is a very fast-paced show. I don’t think it dwells so much on that, and we’re always onto the next case. But from what I can say, she’s in good spirits about it all. I think she has a great support system. She’s got Tank, she’s got Wes, she’s got Raines, Amanda, Smitty."
