'I, Jack Wright's Penultimate Episode Hones in on the Most Likely Culprit

We've only one more episode of I, Jack Wright to go, and Sally’s oh-so-cheery statement at the beginning of the penultimate episode, "Salt in the Wound," is a doozy.

“It’s easy to think that everything that came out - all the greed and the rage and the jealousy was caused by Jack’s death but actually I think most of it was there already and him dying just gave us a chisel to work existing fault lines and the money was just salt in the wound.”

Millionaire Jack Wright died in what was staged to look like a suicide, but was actually murder. His loved ones quickly learn that his will was dramatically changed just months before his death. Some, like his granddaughter Emily, got everything (£15 million, controlling shares of his company, and his desire that she be named CEO). Some, like his son Josh, got nothing (as in absolutely nothing). Some, like his wife Sally, got something that left a clear and not-so-kind message (access to their three homes... but just for the next five years).

As the episode comes to a close, everyone is headed to court to fight for what they think is rightfully theirs. But with every episode, who is guilty and who is innocent shifts. Here's a look at the current odds of being innocent vs. guilty*.

(*This being a British series, we're styling the odds fractionally instead of the usual American way.) 

There are two big reveals in this episode. One is that the texts between Reuben and Emily imply that something untoward happened between Emily and her grandfather, Jack. “If he gave me the whole company, it still wouldn’t make up for what he did to me that night,” Emily had written to Reuben. The implied context of that exchange unsettles both DCI Morgan and Jones. “I hate where this is heading,” DCI Morgan says. 

They question Rose, who puts it bluntly, “You want to know if I thought my ex-husband was a child molester.” Rose is appalled by the suggestion. Jack was a lot of things. He cheated on Rose from “day one” of their marriage. But he was not a child molester.

But I still can’t shake the feeling that Rose isn’t as innocent as she appears. 

Well, well, well. Gray is no longer the boy who cried wolf. The episode kicks off with Bella calling John to tell him that Gray has been attacked and is being taken to the hospital. Now everyone is feeling pretty awful. They didn’t want to give Gray money, but they also didn’t want him to die. 

Gray recovers and maybe realizes the error of his ways. But he still wants the money his father owes him. 

So Emily has 99 problems, and Kyle is definitely one. He’s calling his ex-fiancée nonstop, telling her they need to talk. He still has questions (lots of them!) about the texts he saw between Reuben and Emily. He flies from California to England to confront Emily. He also seems to be in the land of denial because he says things like, “before we can start to rebuild our relationship.” But Emily brushed him off and called him “really f*cking weird.” 

That doesn’t sit well with our friend Kyle, who promptly goes to the police to show them pictures of the texts between Emily and Reuben. They are very damning and don’t paint Emily in a good light at all. (Although all the texts refer to a man, none mention Jack by name.)

Emily goes to Jack’s new lawyer and reveals something. Exactly what we don’t know, but it’s something that only she and the woman who told her knows. “And if I can corroborate this, you are happy for me to stand up in court and use it,” the lawyer asks. Emily is totally fine with that and also has a way to corroborate what she’s telling the lawyer. As the episode ends, Emily says, “None of us has any idea about other people’s internal monologues.” So what exactly is Emily hiding?

So Reuben worked in JK Wright’s mailroom. “We just clicked and have an on/off thing over the years,” Emily describes their relationship to the police. Jack met with Reuben, and three days later, he shredded his existing will, got a new lawyer, and wrote a new will. Emily claims she was not aware of this meeting. The police think Reuben was blackmailing Jack. 

Among his texts to Emily are choice messages, including “Trust me, he deserves everything we’ve got planned and more” and “The look on his face when he has to hand us all that money.” 

When the police finally find Reuben, he answers “no comment” to all the police’s questions. Also, the police know he’s lying and that he wasn’t at his friend’s house the night Jack died. They find blood on a bag and burnt fragments of clothes in his apartment (probably what we saw Reuben burning at the end of the second episode). Is all of this a red herring? Or did Emily, Reuben, and Rose collude to have Jack killed?

The second big reveal of this episode is that  Jack wasn’t Josh’s father. Sally lies to the police about many things, including the last time she saw Arnaud and if Arnaud knew the will was changed. 

Sally’s lawyer is less than thrilled with the news. It clearly proves that, of course, Jack was sane and had a motive for changing the will. 

Sally has no idea how Jack found this out. Whoever Josh’s father is, it’s evidently a traumatic memory for Sally and one that she’s not yet willing to share. 

Josh is caught smoking cannabis at school and, given the school’s policy, that is cause for immediate expulsion. Sally’s policy is that she will make the school’s life a living hell if they kick her son out. “I will fucking drown this school and you personally in so much negative publicity that in six month’s time you will be begging me just to be bankrupted” is how she puts it to the school’s headmaster.  

Up until this episode, Josh has been a sullen teenager grappling with his father’s death and the fact that he was completely cut out of his father’s will. But now we know that Josh isn’t Jack’s son. Josh acts shocked when his mother tells him the truth. But is it just an act? And did he play some role in his father’s death?

DC Jones got the minutes of the last board meeting of Arnaud’s company. Sally was on the hook for a £3 million investment in his company. Sally flat-out asks Arnaud if he killed Jack, and he says no, he was in Paris the night Jack died.  

But Arnaud did see Jack three days before he died, which is not what he originally told the police or Sally. He met with Jack because of what Sally had found on his desk. Sally had apparently seen a DNA test but not seen the results. “Jack was not Josh’s father,” Arrnaud tells her. Arnaud also knew Jack had changed his will. “From now on, you say nothing about me to anyone,” he tells Sally. 

Oh, and he is not letting the £3 million she promised to invest go. 

Gray's near-death has made John see things more clearly. He now understands more what truly matters in life. “Fighting my dead father to prove... he respected me feels like a complete waste of time,” he tells Gray during their heart-to-heart conversation. John never wanted to follow in his father’s footsteps. He wanted to paint and get a fine arts degree. But Jack wouldn’t let him. With this new perspective on life, John gets out his old art supplies and goes all Jackson Pollock. 

He declines to testify at the trial, saying the courts have his statement and that’s enough. He pays off Gray’s debt to Eddie and has Gray live with him after he is discharged from the hospital. After Gray is fully recovered, John tells Georgia that he thinks they need a break and moves out. (All of this goes a long way to explain why John looks more like Noah Kahan and less like himself two years later.) 

In the future, John says, “Sometimes I think you would have to be slightly mad to be sane.” So, where exactly is John’s interview taking place?  

We don’t see much of Georgia, who is not thrilled with John’s decision not to testify in court. But she does make a mysterious phone call and says to the person on the other end, “I just wanted to say I really miss you and I would love to see you and I wonder if you can ever forgive me.” 

Apparently, we don’t talk about Asha, no, no, no, because she wasn’t mentioned at all in this episode. Which makes me think she might be someone we have seen but don’t know is actually Asha. Like, perhaps Mary, the house manager? The one who covered for Gray when the police initially questioned her. We’ve never seen her with anyone else but the detectives.
