Nina’s mistake sent Jack Brennan to the hospital and left her staring at the fallout from two dangerous choices on Monday’s episode of General Hospital. She accidentally injected the WSB agent with the medication Willow has been using to keep Drew in a paralyzed state, then realized too late that Drew had missed his scheduled dose.

Cynthia Watros called it “not a good day for Nina,” and the scenes did not sound any easier behind the camera. She said they were fun to shoot, but also described the setup as tricky, with Nina trying not to be caught in the middle of the fight between Valentin and Jack before ending up injecting Brennan with the paralytic. Watros said the three actors worked with a fight coordinator.

After Jack collapsed, Nina followed him to the hospital and did not stay to tend to Drew. That decision matters because Drew’s failure to get his injection on time could carry huge consequences for Nina and Willow. Watros said Nina only remembered once she was at the hospital, then called Willow to say Drew had missed his dose. “She freaks out,” Watros said of Willow.

The incident lands at a dangerous moment for Nina, who is already tied to Willow as an accomplice in crimes against Drew. Brennan was alive but far from well by the time Monday’s episode aired out the aftermath of the Friday cliffhanger, and Nina is now facing what Watros described as potential charges. That is the part Nina cannot dodge: she hurt Jack Brennan, and he is in a hospital bed because of her.

Watros said Nina is terrified and thinking first about her daughter, then about how the situation affects her. She also said Nina and Willow both know it would be very bad if Drew starts moving again. Watros praised Cameron Mathison’s performance as a locked-in Drew, saying, “Cameron has been doing an amazing job” and that “Drew is afraid with his eyeballs.”

What makes the mess even sharper is that Nina did not mean to put Brennan there. Watros said it is not in Nina’s nature to put someone in the hospital because of something she did, and that the moment may even leave her with more compassion for him. For now, though, Nina is left with the kind of day that ends, in Watros’s words, with a hot bath, a glass of wine and a need to decompress.
