I don't get many things right the first time
In fact, I am told that a lot

Eragon flinched involuntarily remembering the day under the Menoa tree, when Arya had shunned him, how hurt he had been, and how he'd wished he had never spoken in the first place.

Now I know all the wrong turns, the stumbles and falls
brought me here

He spun Arya around, seeing the joy on her face, hearing her beautiful laugh, and he couldn't help but laugh with her, attracting the attention of the other elves.
And where was I before the day
that I first saw your lovely face?
Now I see it every day
that night, when she had come to his tent, when Saphira had mysteriously wanted to go hunting, though Eragon knew she had gone earlier that day.

And I know
She had looked around, clearly ill at ease, and he had gone to her, without thinking, touching her shoulder,
that I am
I am
I am
the luckiest

He had a lifelong mate, he was a Rider, and Galbatorix was dead. He thanked the stars every morning for those things, knowing that he shouldn't have survived the battle at Uru'baen.
What if I'd been born fifty years before you
in a house on a street where you lived?
Maybe I'd be outside as you passed on your bike
would I know?

Trying out that insane contraption Orik had come up with, both of them crashing repeatedly, laughing as they healed their wounds, and he wondered, what if I had never found Saphira? I would not know half the people that I know, I would not have a mate, neither of us would be Riders, and it was almost too much for him to process

And in a white sea of eyes
I see one pair that I recognize

He thought back to when he had first dreamed of her, how painful and lost those emerald orbs had seemed,
And I know
He vowed that she would never feel such pain again for as long as he lived
That I am
I am
I am
The luckiest
The tears of joy in her eyes as Bailey took her first steps, falling into her father's arms, Arya clapping, the dog running in hyperactive circles, and Eragon looked into his daughter's warm chestnut eyes as she giggled, black pigtails bouncing,
I love you more than I have ever found a way to say to you
Next door there's an old man who lived to his nineties
And one day passed away in his sleep
And his wife; she stayed for a couple of days
And passed away
setting flowers at the base of Nasuada, Murtagh and Thorn's statue, mercury tears streaming down silent faces as the crown was set on Roran's head,
I'm sorry, I know that's a strange way to tell you that I know we belong
here, under the green boughs of Ellesmera, Bailey would be able to grow up safe, a normal elf, playing with her dog, and singing to flowers

That I know
Many elves scorned their relationship, treating Bailey as an abomination, but Eragon would never leave Arya's side as long as she wanted him, he would be there, as he had when they watched the fallen warriors lowered into the ground, families watching, tears marking grief beyond compare
That I am
I am
I am
The luckiest
