I would sort of like to see the damage control that Peter was able to do in LWW in between the ill-fated hide and seek game and the day of Mrs. McCready's tour. 

Especially since they all seem to be on good terms again and Edmund and Lucy are able to be in the same room without coming to blows.

Did Aravis find her brother? Perhaps even her mother?

If the criteria is that "they looked in Aslan's face and loved him," we might well be surprised. The majority of people on Planet Narnia never had decent nurture or training, as King Lune said.

I'd expect the most likely candidate is the sl@ve-secretary who helped Aravis. Clearly he cared more for her than did her father.

So, how did the Calormene Carson (DOWNTON ABBEY reference) find out that his little girl was safe and happy? I'd assume the Tarkaan reads his mail, so no mail there. But maybe a Talking Bird could slip through and tell him quietly in the garden. At minimum, there must have been gossip and a flurry of outrage among the Calormene nobility when Crown Prince Cor married the Lady of the Southern Stars. Ten years after her crass family would have married her off, by the way.

Speaking of...what about Aravis's friend that she met up with in Calormene? I liked how despite seeming rather shallow, she ended up being a good Samaritan and helping Aravis escape. It's very sad to think this was the last time either saw each other, even if they were both happy with the different lives they'd chosen.

It is sad, and we are fond of silly Lasaraleen!  Perhaps we can hope that somehow she encountered Aslan...  but as He always said he was telling the listener their own story, not others', so we will just have to imagine.

Here is one mystery that I have always wondered about.  I don’t know how the lamppost remained lit all of those years after it was transported from Earth to Narnia. Was it lit by magic or something else?  It is true that things that were moved from our world to Narnia somehow came up from the ground during Narnia’s creation, but how could it have been lighted for hundreds of years without burning by gasoline or some other kind of fuel? To our knowledge there was no electricity in Narnia, and there were no inventors like Thomas Edison. There was no explanation for artificial lighting in Narnia’s creation, which may not have been necessary with Aslan’s provision.  We don’t know if candles were used or how they could have been made.  There were fires used, but we don’t how they were ignited. I guess we must assume that the lighting of the lamppost was done by magic.  🙂

I would guess that whether or not she met him during her "earthly" life, she definitely met him face to face after her death, as we see happening in The Last Battle — and Emeth's encounter with Aslan illustrates it more fully. The final judgment of each individual in the Narnian world is based not on whether or not they knew Aslan (or at least knew of him) and pledged their allegiance to him in the mortal world, but on how they respond to him when they find themselves in his presence: do they hate him, or love him?

And — as with all the other characters we're not told about at the end — we don't know what Lasaraleen's response to him might have been. But silly and shallow as she was as a young woman (we don't know how the rest of her life panned out!), she did have better qualities — as @nicemice2023 says, she did the right thing by helping Aravis to escape — and I like to think that, like Emeth, she would have recognised Aslan as the only one truly deserving of honour, when she met him at last. 

Moonwood the Talking Hare with the amazing hearing is mentioned in passing during the Last Battle, and there has to be a story or two there. Who knows if Lewis ever intended to expand on that character later?

Speaking of the Last Battle, Erlian seems like a good kindly king/father, and reminds me of Lune. But we don't learn anything about him other than that he fed Jewel apples, that he played with a young Tirian in the courtyard, and that he suffered a fatal injury fighting a giant.

I wondered if some places in Narnia could have been used in more than one book. The place where Jill and Eustace first arrived in The Silver Chair and near the end of the book where Aslan brought King Caspian back to life was to my knowledge used only in that book.  But it certainly did exist until the end of Narnia in The Last Battle.  Or was it just a transitional place like The Woods Between the Worlds in The Magician’s Nephew?  Some of the other places were intriguing like the cliff where Eustace and Jill had their disagreement before Aslan blew Eustace to Narnia and Jill received the signs. It makes you wonder why they were mentioned only in one book when they seemed like very magical locations.  But Lewis may have thought that the magic would only work for one story as with the wardrobe in the The Lion, the Witch, and the Wardrobe. Still, the locations would be worth visiting again. 🙂
