"Yeah, sure. Be right back!"

Nobody interrupts her back on the way to the lookout.

"Aaarrryyylllll!"

"Aaaaanna! I have a present for you!"

"Ooh, a present!"

Aryll waits for her to finish climbing. "...Wow those clothes look really warm. I guess they're neat though. Grandma made them I guess?"

"Yep."

Anna preens, a little bit. She is proud of her new clothes.

"Anyway, here is your present! Not only did I made you this ribbon but also you can use my telescope for today! Make sure to take good care of it." She holds out the items in question. The ribbon has a slightly crude picture of Anna, Aryll, and Grandma all holding hands sewn into it. The telescope has seagulls painted on its side.

"Aww, thanks. Best sister!" Hug time!

Hugs!

"Let me show you how to use the telescope! You look into it and point the big end where you want to see, of course, and then you can slide this piece to zoom in. Oh, the post is here! Look at the mailbox down there!"

There is a bird-person delivering mail to said mailbox.

"There's a delivery!"

The postman sees something, looks alarmed, and flies away.

"AAAHH! Anna! Look up! Look up!"

"KRAAAAAA!"

That... Is a monster bird carrying someone in its claws!

And an honest to god pirate ship chasing after, flinging cannonballs at it!

AAAHHH!

"Aryll stay down!" Anna takes off running after the bird.

The giant bird drops the girl it was carrying after getting smacked in the face by one of the cannonballs. She falls into the forest at the peak of Outset Island.

Then Anna will go up after her.

No she won't. There's thick brambles blocking the way. A knife or sword of some kind, or even a torch, would make quick work of them...

Doesn't Orca, the old guy who promised to teach her to fight, have a sword?

Hmm. All right. Orca's first, then she'll go after the girl.

Orca is hitting things with a wooden stick in his room. Which is right below Sturgeon's and attracts complaints of a racket from him.

"...What's wrong, young one? That expression is far too serious for such a day as this."

The words trip out of her in a great rush. "There was a pirate ship chasing a giant bird and the bird had a girl but it dropped her at the top of the peak and I want to go make sure she's okay but I can't get there because the brambles are in the way. So can I borrow a sword?"

"I see! This is a matter of great import! However, it would not do to simply let you borrow a sword without knowing how to use it. I will let you have it after I teach you to fight." He sees her expression. "Quickly teach you, that is."

"Right. Okay, let's go."

He gives her a wooden practice stick and takes up his bigger stick and has her bow in the correct way despite her impatience. 

He shows her various combinations of moves and asks her to repeat them to his satisfaction, using him as a target. "Do not fear that you will hurt me."

She's a quick study with the blade. She gets all the moves in one or two tries.

He makes her practice each a couple dozen times, expanding the repetoire to include showy things like a spin attack and a jump slash.

"Good! You are good at this. Now I will show you the most important part of fighting. The parry! Focus on me and push your surroundings aside. Then, wait for me to attack. As soon as I move, dodge and counterattack! This technique will be invaluable to you if you ever need to truly fight."

He backs up and waits five seconds then comes at her with a "Kyaah!"
