To me Saga is April reborn. The spirit that was April became Saga. Remember Abnaxious sees the past present and future simultaneously. One spirit, two individuals. Saga is not April and April is not Saga. The spirit that was April then became Saga after April died. While Saga is not aware that she had a former life as April, she senses some connection to April she does not understand. The spiritual side of her nature knows the connection even if she does not.
April: I'm guessing...I'm pretty sure, actually...I'm not in Venice anymore. Now I know how Alice and Dorothy felt. "Moby Dick", "Oliver Twist","The World According to Garp","Zen and the Art of Motorcycle Maintenance","The Holy Bible"...It's an eclectic collection, that's for sure. I don't know who she is, but she does look vaguely familiar.
Why would April say Lady Alvane looks vaguely familiar. There is no reason if there was not a connection between the two. The connection being the same spirit.
Old Woman: Welcome, April Ryan.
April: I won't ask how you know my name...but who are you?
Old Woman: The Lady Alvane is my name now.
April: And where am I? What's this place?
Old Woman: This is my home, the House of All Worlds.
April: This is Arcadia? It looked like I passed through a Shift but it didn't feel...it felt different, not like Shifting.
Old Woman: It's similar to Shifting, except you did not pass through dreams, and you're not in Arcadia, not in Stark. This place is Between, and Everywhere. But don't worry. You are safe from your pursuers. For the moment.
April: Did you bring me here?
Old Woman: You brought yourself here, but yes, I opened a doorway for you.
Why use the expression "You brought yourself here"? April thought she had opened a shift to Marcuria. It is not like she had chosen to go to the HOAW.
Old Woman: Because that's how the story goes, April. You escape. You outrun your pursuers, and your journey continues. It's been written, and we cannot change that now.
April: Lady Alvane, I appreciate your help, but I'm so tired of hearing about my destiny, and about prophecies...I've lost a good friend today, and...
Old Woman: She's not dead.
April: What...what did you say?
Old Woman: Emma's not dead. She was hurt, but not killed.
April: Oh, thank God. Are you sure?
Old Woman: I'm quite certain. She is on her way to the hospital as we speak. But the others, Charlie, Fiona...they're angry at you. They blame you for Emma's pain and for not letting them in on the truth.
April: They should blame me. I brought it all to them, the violence, the chaos...I've hurt so many people since this all started, and yet at the same time it all seemed -- justified.
Old Woman: It was. The fate of many depend on the sacrifice of the few. Your sacrifice most of all. You've made so many, and you'll have to make many more before this is all over.
April: Will it ever be over?
Old Woman: Eventually. The pain won't go away, though, You'll keep that with you forever.
April: I don't know if I can go on. It's so hard.
Old Woman: Listen to me, April. You must go on, you must be brave. They all depend on...on you. (I always thought this hesitation was odd, there is no reason to hesitate to say the word you, unless she was going to say something else and caught herself.) And you can do it, you can get through this. Just remember what's important and what's not. Remember who your friends are, and trust them, let them help you.
April: I already did that, and look where it got them.
Old Woman: Somebody gets hurt. That doesn't mean you can give up. I want you to go to Marcuria, to see for yourself how those who are not willing to surrender are holding up. You can learn from their courage.
April: I can't go there. I can't Shift. People tell me I have this.... This talent but it's not true. If I can't use it, what good is it?
Old Woman: But you have used it twice already! April, child, you must learn to believe in yourself and your abilities, use what you know, what you do best, to focus your magic.
April: What I do best...you mean painting?
Old Woman: If that's what you do best, then yes, use that as a focal point. After a while, you won't even need that, but it's a beginning.
April: What about the other things I have to do? What about the Guardian?
Old Woman: The Vanguard are holding Adrian, the Guardian, captive. But they still don't know where the entrance to the Guardian's Realm is located.
April: Shouldn't I free Adrian immediately?
Old Woman: Go first to Marcuria. The doorway will bring you there. If you go straight back to Stark, the Vanguard will find you.
April: Thanks, Lady Alvane. I'm not gonna ask you how you know everything you just told me, because I'm not sure I want to know.
Old Woman: Good luck on the journey ahead, April. I will...keep my fingers crossed for you.
April: Maybe I'll see you again?
Old Woman: Oh, I'm quite certain of that. Quite, quite certain.
Sunday, August 5th, around mid-day
and my life was hanging by a thin thread this morning. If the Lady Alvane hadn't "invited" me to her house (by way of what looked like a Shift), I would have been captured and maybe killed by now. She also told me Emma will be okay, and even though I can't be sure she's telling the truth, I trust that she is. There was something about her, something so disconcertingly familiar that I can't help but trust her implicitly. Not to mention the fact that she helped me out when I most needed it. It's really strange how much she seemed to know about me, and it's so frustrating that she wouldn't tell me more. At least she brought me here to Marcuria, to see how people are holding up in the face of war, and I guess, to complete the disc. I wonder who stayed on? Tobias, maybe. Or Abnaxus. And Brian. Can't forget Brian. I'll have to go visit them all, one last time.
As I said earlier why does she find her familiar? There is really no reason, they have never met before this encounter.
Lady Alvane has things of April, but why and how? And the drawings she made of Aprils life when she was young, there really is no reason unless she is April reborn as Saga.
Finally, we see a reborn Crow with Saga. Since she really didn't know Crow why did she go out of her way to pick up his fallen body, unless her spiritual side which retains the memories of Aprils life was guiding her? The reborn Crow is drawn to Saga because his spiritual side knows April and the spirit that led the life of April is now leading the life of Saga.
But lets say Lady Alvane isn't April reborn. April told both Kian and Zoe she wanted to be reborn and if she did not become Saga/Lady Alvane, who did she become? I see no hint in the game pointing to another person as being April reborn.
