It's Event Number 222. Code: 0_04_01_1.
I am most certain that this event is supposed to be activated in Dr. Black Jack's house, since that location is identified by the code '0_04'.
And upon closer observation, I think that it could either be an alternate dialogue scene, or a "Oops, you did something wrong, go back" scene, as Event 223 is identified by the similarly-titled code "0_04_01_2".
Event 223 is like this:
Astro Boy: Are you Dr. Black Jack?
Black Jack: Yes. Is there something I
can do for you?
Astro Boy: I could use your help in
an operation. You see...
Ham Egg: The doctor doesn't operate
on anyone anymore.
Astro Boy: And who are you?
Ham Egg: Me? I'm his bodyguard,
err..., I meant manager.
Astro Boy: What?
Astro Boy: Doctor, are you being
threatened not to perform
any operations?
Black Jack: It doesn't concern you,
so just leave!
Astro Boy: I'll use my Hyper Sensors
and see if I can figure out
what they're saying...
Ham Egg: Good job, Doctor.
Ham Egg: All you have to do is to
continue not to operate.
Black Jack: You...!
Black Jack: If anything happens to
Pinoko, I'll tear you
apart.
Ham Egg: Oh, how scary. Calm
down doctor. Of course
she's safe.
Ham Egg: She'll be fine as long
as she's under the
watchful eye of Skunk!
Astro Boy: Skunk? I've got it! She
must be on Cruciform Island!
The thing is, I still cannot figure out how to activate Event 222. As far as I know, there is no way to try to go into Black Jack's house earlier than the norm, and revisiting his house after doing all sorts of things just continuously replays 223. Also, once you go to the moon with Black Jack to operate on Prime Rose, there is no way to return to his house until after you beaten the final boss. And even if you do revisit after completing the game, it'll just replay the event where Hamegg sends a gigantic Roboid after you. In short, I feel like I've tried everything. Event 222 is like the bane of me, and I really need some assistance if I am to complete my Game Script guide.
Even if you already have the event recorded and just write it down here, I'll also have to know when and how exactly it is activated, since I am writing events in encounter order in my guide, not by Event Test's order. Also, to anyone who helps with this, you shall be credited in my guide as well.
Thank you.
