We Finally Know Who Killed Elena Alves on The Undoing — Are You Surprised?

After that major cliffhanger during the fifth episode, things aren't looking good for Henry (Noah Jupe). In the final moments, Grace ends up finding a hammer in Henry's bedroom that looks a lot like the missing murder weapon. Henry is shocked when he notices his mom's discovery, but could Henry actually be behind Elena's murder? I mean, he did recently confess to knowing about his dad's affair with Elena, so that does seem like a motive.

However, he also could just be covering for his dad. Given how close they are, it makes sense that Jonathan could have asked him to hide the murder weapon in his closet, since nobody would ever think to look there. It's later confirmed in the finale that he indeed was covering up for his dad and had nothing to do with Elena's murder.
