Just a thought on the whole Arwen plot change whilst I agree she should not of ended up at helms deep… If she went to Lorien and looked into Galadriels Mirror as planned whilst the council of elves took place or after and then she has the vision of the child that would make sense…

So then the argument she has with Elrond about not telling her there was a child makes sense.

What do you think?

I am struggling to understand or even find a good reason for this being changed actually… Unless it was just running time rather they just did it a different way?

Ok I think I have it or sort of have it…

So there’s enough research on the Internet to make a lot of conclusions as to what Arwen’s original role was intended to be.

FOTR

Gilraen’s Memorial originally had a second part of the scene that ended with Elrond pushing Aragorn to cut things off with Arwen so that she would go to the Undying Lands. This deleted scene ended up in TTT as a flashback.
Arwen and Aragorn’s “breakup” was originally shot for FOTR, making more sense of Arwen’s farewell shot that is still present in the Extended Edition
Aragorn tells Galadriel he wants Arwen to go into the West

TTT

Arwen’s vision in ROTK was originally in the first half of TTT, prompting Arwen to return to Rivendell and set off a chain of events that would send…
Arwen and Elrond to Lothlorien, where they confer with Galadriel
Arwen and Galadriel have a private scene of some kind…

what if the vision of the child she would have with Aragorn was from Galadriels Mirror in Lorien?
In the Two Towers when we see the Flash Back to the original plot excised from fellowship of the ring What if this was Arwen Leaving for Grey Havens then as Eowyn asks “Where is she”… That then increases the Love interest for Aragorn and Eowyn. Aragorn thinks about moving on… But she finds another reason to return to Rivendell perhaps because she senses Aragorn is in trouble as he goes off the cliff as he loses the Evenstar at this point the connection between them is broken.

The voice over on frodo suffering the Morgal Blade “let him have my lifes grace” from Arwen may very well have been meant for Aragorn near death as that is extremely confusing and makes no sense at all.

So as Arwen bolts back to Rivendell fearing Aragorn was to lose his life we then see the Balcony scene from the trailer “you have given up your lifes grace I can no longer protect you”

When Aragorn is in a bloody mess by the river perhaps Arwen and Aragorn about a good dream and the snogging then cut to the horse waking him up good gag that 😃

Elrond accepts that eventually Arwen has made the choice she has made and he takes her to Lorien where the council meeting takes place where Elrond is the one to persuade the Elves to help out and send Haldir. Elrond leaves but Arwen stays in Lorien.

Arwen feels lost about her decision knowing that Aragorn still might die in the near future or if the ring goes to Sauron she will fade quick so she looks into the Mirror of Galadriel when she sees that there is a child she rides back to Rivendell on these tiding of hope that a better future can be found. She also sees the ghosts which she does not understand…

Arwen confronts Elrond about she never told her there was the possibilty of a child.
this triggers the Re-forge the sword and the research of the paths of the dead to change the outcome and the intervention required for the future she saw in Galadriels Mirror. Seeing as they intervened at Helms deep they felt they could sway the outcome again with their actions.

The Even Star Breaks when Aragorn looks into the Palantir and Arwen begins to Fade Aragorn must fight Sauron in physical form although when the ring is destroyed I imagine he would disintergrate and the eye on the Tower would light up. Interestingly looking at the Hobbit Eye of Sauron where you can see a feint physical form wreathed within the eye seems like a unused concept to show his power growing.

That is perhaps my brief take but hey, who knows?

Ultimate cut won’t happen by Jackson but with any hope the deleted scenes will be shown.
