Do you mean something like.... this?:
Prologue
Scene: Black screen
Janus: Mother, No!!
Zeal: Janus? what are you doing here? Go back to bed!
Janus' Father: Ja..nus..., go... g-get.. h..e..l..p..
Janus: Father!? FATHER!!!!
Scene: Zeal Palace, Prince's Quarters. Janus wakes up in his bed, covered in a cold sweat. Schala is beside him.
Schala: Calm down, Janus. You were having that nightmare again.
Janus: It happened, you know. She killed him... with the Black Wind howling beside her... she killed him.
Schala: Everythings going to be Ok, Janus.
Janus: How can you say that?
Schala: As long as you keep hope, anything is possible.
Scene: Schala gives Janus a hug and then leaves. Scene fades out. Janus is woken up by Schala the next morning.
Schala: Hey, do you want to go visit the Earthbound today?
Janus: Why would we do that? Mother says that they're inferior, and their caves stink.
Schala: They're just like you and I, Janus. They just don't have magic, and they stink because we won't let them up here to bathe and look presentable.
Janus: If you say so...
Schala: Oh, come on, please?
Janus: Ok.
Scene: Janus and Schala go to leave, but are stopped by Gespar, the Guru of Time.
Gespar: Schala, the Queen knows you go to visit the Earthbound, and she allows it. But if both her children were to do it, she would take offense. She allows you to go insofar as it keeps you happy.
Schala: What are you suggesting?
Gespar: Let Janus come with me while you go down to visit them. I will keep him out of harms way, and you stay below the Queen's immediate concern. Trust me, you do not wish to be one of her immediate concerns, my dear.
Janus: Please, Schala! I'll behave, I promise!
Schala: ...Ok.
Gespar: And Schala, if it is a boy you are seeing... Well, it should go without saying what would happen if...
Schala: I understand Guru, and that is none of your concern.
Gespar: Very well, Schala. Let it not be said that you were not warned. Come on Janus, today we're going to visit Kajar.
Janus: Yay!
Scene: Janus & Gespar and Schala split ways and the scene fades out. Comes back in on the Guru's Private room in Kajar.
Gespar: Do you understand what a secret is, Janus?
Janus: Yeah, it's something that you hear that you never tell. Schala told me!
Gespar: Very good. This room is a secret, Janus. A secret between you and I. You must not tell anybody.
Janus: Not even Schala?
Gespar: I'm afraid not, Janus. Your mother, th-
Janus: She is not Mother.
Gespar: You are perceptive. She is your Mother, but she is not the same as she used to be. She has grown...
Janus: ...monstrous
Gespar: Indeed. Which is why we Guru's have need of secret rooms like this. We are wary of this beast 'Lavos' that she communes with. It has a very powerful energy but-
Janus: But it feels so bad.
Gespar: Right you are. It has been corrupting the peaceful aura of Zeal since your Mother built that Mammon Machine. I don't know if you knew, but your father... he could feel the evil energy just like we feel it. He went to stop her..
Janus: ...I know...I...I was there.
Gespar: ! That is terrible! I am truly sorry that one your age would have to witness something like that. But you can see why we do not openly resist her.
Janus: Yes.
Gespar: Come though, enough talk about these things, I want to show you something.
Janus: What is it?
Gespar: This is something I've been working on. It is a 'Time Egg', a Chrono Trigger.
Janus: What does it do?
Gespar: It has... well, it WILL have, the ability to repair lost strands, lives, if they're important enough in the grand scheme of things.
Janus: Could it... could it bring back...Father?
Gespar: I don't know, Janus. It is still unfinished. There are a lot of tests to run and a lot of errors to fix before it is finished. I showed it to your Mother once, in it's earliest phases, but she was not interested in bringing the dead back to life. No, she was more interested in keeping the alive... Alive. Forever. But enough about that. It's been a long day and I think your Sister should be back about now. Let's go meet her at the gate, and we can go in together for some cookies.
Janus: Yay! Cookies!
Gespar: Haha, energy seems to be wasted on the young. No matter, let's go.
Scene: Scene fades out. Comes back in on the Prince's Quarters, next day. Schala wakes Janus up again.
Schala: Janus, Janus! Mother says that the Ocean Palace is finished. She wants my presence down there.
Janus: Can I go, too?
Schala: No, it would be too dangerous, you must stay here.
Janus: Awwww... come on.
Schala: I'm sorry, Janus, but you can't come with me this time. Here, this will keep you safe.
Janus: Your amulet?
Schala: It will protect you when I'm not around.
Scene: Schala gives Janus a hug and leaves. Player is now free to move Janus around, but only in Zeal Palace. activation for the next scene is in the Throne room, where Crono and Crew made their way down to the Ocean Palace. There, Janus walks in just in time to see the three Guru's go through the portal to the Ocean Palace and follows. Player still keeps control of Janus through the Ocean Palace. No fights, just simple walk through, up until the last room, where Zeal, Schala, and the Three Guru's are located.
Zeal: Janus! what are you doing here, you bad little child! You're just as bad as these Guru's, sticking your nose where it doesn't belong. All of you, get OUT of my SIGHT!
Scene: Lavos chooses this time to become active and sucks the three Gurus and Janus into Time Gates, sending them each to different era's: Belthazar to the far reaches of 2300 A.D., Melchior to peaceful 1000 A.D., and Gespar to the mysterious End of Time. Janus ends up in rural 600 A.D. surrounded by imps and a curious Ozzy. The Imps attack Janus, beating him nearly to death, when suddenly a power inside reacts and vanquishes them all. Ozzy scoops the child up and takes it back to his Fort.
