About Hayakawa current status after being brainwashed and transformed as Naoko

Hello there After lurking on reddit for years (since 2019). I decided to create an account.

Since i'm really far behind in Pumpkin Night story with two stories i remember reading. Was back when Kazuya and his team went to Okinawa then they later got ambushed while on the island with that subsequent gunfights which resulting in him getting gun down later on.

Now, I looked at how's the story going by skipping to Raw version of CHP 129 and 153 and Why i'm skipping to those chapter ? Well, simple. i'm really sad at what happen to Hayakawa. After regaining hee memories she just looks like running from her superior and ended up living on black haired guy she encountered.

So here's my question. Its fine, if got its paragraph long answers.

1. Choker, What is this for ? Controlling the wearer only ?
2. At which Chapter Hayakawa got abducted by Larry ? Or she got abducted off screen ?
3. After she run away from her superior, the doctor and Jun, What Hayakawa planning to do now ?
4. I read raw, it looks like she completely regained her memories back. Is that true ?
5. How are they going to removed that Choker ?
6. On of her memories on Chapter 152, she saw a couple of husband and wife with them holding a child that looks like her. Is that the memory of when she was an infant ?

Thanks for anyone can answer these six of my questions.
