I know, Murtagh swore to Eragon in the Ancient Language that they were brothers, son of Morzan. But... if he didn't know, he wouldn't be lieing, right? It never said that Galbatorix told MURTAGH that they were brothers in the Ancient Language, he could have told him in a normal language. If he did, Murtagh would have probably still believed him, since it sounded possible, and it was true in his mind. When he told Eragon, he was perfectly sure about it, so he was not lying, so he would be able to say it in the ancient language....

yes, they are, they are brothers, only elves can tell in half truths in the AL

Half Truth means you aren't telling everything that is to be told. Eragon did this, and he's not an elf. And anyway, it would be the truth, as Murtagh knew it, and that's what matters.

yea as long as you think its true then you can say it in the AL

there weren't twins. Murtagh is older. and *sigh* i have said this forever... here is my boatload of evidence:

Brom said, “She was full of dignity and pride, like Garrow. Ultimately it was her downfall, but it was one of her greatest gifts nevertheless. . . . She always helped the poor and the less fortunate, no matter what her situation.” He answered to Eragon’s question, “You knew her well?”, “Well enough to miss her when she was gone.” Also, Blagden said “Son and father alike, both as blind as bats” after being asked what his first prophesy ment. This denotes that Blagden had met Eragon's father. Morzan had never gone to Ellesmera, though Brom had. On pg. 435 of Eragon, Angela saya, "He (Brom) loved a woman, but it was his affection which was her undoing."

So what happened was she was carrying Brom's child and Morzan found out. She went to Carvahall and had Eragon. She then ran off, running from Morzan, was caught, and then killed. This enraged Brom and Brom went and killed Morzan. Later, he went to Carvahall to keep an eye on his son, Eragon.

that is the lot of it. it's enough to prove it. i've lost track of how many times i have posted this evidence for my theory.

totaly agree with you there.

think they are half brothers
morzan is murtaghs father
and brom is eragons

That is probably the one thing everyone agrees on.

yeah but then again i think everyone agrees that Eragon is not going to go evil
because that would be stupid

"Thinks for a sec"

...nah, it is stupid.

yea there is not way eragon would go evil
