Plot summary
The Graysons devise a plan to dispose of Helen's body without the Initiative figuring out Victoria killed her. Since their plan will make the Initiative believe Helen left the Grayson home alive, they plant evidence to make it look like Helen was at Amanda's before she disappeared. Emily finds out Nate Ryan is on the boat and knows he's up to no good. She and Nolan take off to track the boat. Once Jack and Amanda discover Nate Ryan is on the boat, they think of ways to distract him and finally lock him in the boat's cabin so they can get in the emergency raft and escape.
While Nate is shooting through the door to get out, he shoots Jack. Amanda stays behind and sends the raft out with Jack inside so he'll be safe. Emily and Nolan find Jack, and Nolan takes him to the hospital while Emily goes to save Amanda. Amanda and Emily fight Nate; a stray bullet causes flammable fumes to leak. Emily makes it out, but Amanda gets hurt in the explosion. She later dies in the water. Padma tells the Initiative she wants proof that her father is alive, before continuing to help them. They send a finger of his to show her that they're not to be questioned or disobeyed.
