Ok but the subplot where Aragorn becomes the protagonist of a Horse Girl Movie⢠is one of my FAVORITE things to come out of the Two Towers.Â
In the stables of Rohan, there is an unruly horse named Brego. This horse is so wild that even the horse-masters of Rohan canât tame him. Heâs just a lost cause, they say. âThereâs nothing you can doâ leave him,â they say.
BUT THEN ARAGORN COMES IN. And like the heroine of a Horse Movie⢠heâs all: âYou just donât UNDERSTAND the horse! The horse is wild and rebellious and freeâ like me!âÂ
Aragorn begins gently talking to the horse, first in Rohirric, then in Elvish. He calms him down and asks him whatâs wrong.
You could easily draw a parallel between Aragorn and Bregoâs ârebelliousness.â To Theoden, Aragorn was acting overly unruly and difficult.  âWhen last I looked, Theoden, not Aragorn, was King of Rohan.â Then Brego acts unruly and difficult â and Aragornâs like âthe people of Rohan just donât understand you!!!!!!â
And then Eowyn explains that Brego used to belong to Theodred.
Suddenly Bregoâs unruliness IS completely understandableâ his master was killed in battle. Heâs a horse with a Tragic Backstory.
âYour name is kingly,â Aragorn tells the horse. Aragorn is also a king. Aragorn is projecting.Â
Now that sheâs explained the horseâs tragic backstory, Eowyn tries to get Aragorn to open up about his own Tragic Backstoryâ˘. (âI have heard of the magic of elves, but I did not look for it in a Ranger from the northâŚ.?â) She fails. Aragorn is briefly like âyup I was raised by elves,â does not elaborate, and then peaces out.
But as he leaves Aragorn dramatically says: âturn this fellow free; he has seen enough of war.â Â
And Eowyn is forced to wonder whether Aragorn is talking about the horseâŚ.or about himselfâŚ.
Then Aragorn has a Near-Death-Experience, but Arwenâs elven-magic (just roll with it)Â saves him. And the horse who comes to carry him to safety is none other than Brego.
Itâs Brego, repaying the kindness and understanding Aragorn showed him earlier in the film!Â
 Aragorn set Brego free, and in return Brego saves Aragornâs life!
 Because they UNDERSTAND each other, as fellow free spirits who âhave seen too much of war.â  Both of them are KINGLY but also WILD, theyâve lived through too much and lost people they cared about, and their strong wills cannot be tamed by anyone in Rohan!
 Itâs beautiful. Aragorn canonically has Disney-Princess-level animal friendship powers.Â
When they arrive at Helmâs Deep, Aragorn smiles and earnestly says in Elvish: âthank you Brego, my friend.â And we know that Brego understandsâŚ.
