‘The Undoing’ Episode 6 ‘The Bloody Truth’: Will Grace turn herself in to protect her son after discovering hammer?

Spoiler Alert for ‘The Undoing’
Shock, suspense and serendipity... HBO's ‘The Undoing’ has all the ingredients for a perfect whodunnit crime series. The fifth episode ended with two shocking discoveries: Jonathan Fraser (Hugh Grant) is a psychopath and Henry Fraser (Noah Jupe) has the hammer hidden in his violin case. What will Grace Fraser (Nicole Kidman) do after finding out these shocking clues about her husband and son?
In the episode, Grace gets a face-time call from Jonathan's estranged mother and mum-in-law drops a huge shocker. Grace addresses the tragedy from Jonathan's past of how his sister died and the blame was on him. His mom then tells her that he expressed “neither guilt nor grief” and hints how he turned into a sociopath. As the episode draws to a close, Grace tucks her son in bed and discovers the hammer while putting his violin back into the case.
What will Grace do now? If Henry really turns out to be the murderer, will she turn herself to the cops to save her son? Or was it Jonathan who hid the weapon? One fan said, “Not being adequately mothered by you Grace! That's what he's doing. The child needs therapy and he needs his Mother. You've done your Queen Of The Night routine. Now do your mothering routine Grace,” and another posted, “Remember when Jonathan came into Henry's bedroom to say I love you before his '5 am flight' to the Cleveland conference? He hid the hammer there and asked Henry to cover for him with Grace, then he fled. He's a psycho!!”
"...What are you doing!?"

Remember when Jonathan came into Henry's bedroom to say I love you before his "5 a.m. flight" to the Cleveland conference? He hid the hammer there and asked Henry to cover for him with Grace, then he fled.
He's a psycho!!

Back when Grace first discovered Jonathan had cheated on her and he came to meet her at their beach house, Grace called the cops on him. So, it seems unlikely she will take the blame for a crime that Jonathan committed. The real twist could be if Grace herself turns out to be the killer. Perhaps, she could have a change of heart and turn herself in to save her son.
Going by the episodes that have already aired, the plot seems to be much thicker and confusing than the book. It seems the killer would turn out to be someone we least expect. Who do you think is the real killer? Tell us in the comments below.
