Which sentence in the text best suggests that Robert and Andy have a strong relationship?

Beyond the Horizon
by Eugene O’Neill (excerpt)

In this opening scene, Robert is preparing for a journey at sea with his uncle. He dreams of leaving his family farm to seek adventure. His brother, Andrew, enjoys his life working on the family farm.

ANDREW: Well, the trip you’re leaving on tomorrow will keep you moving all right. (At this mention of the trip they both fall silent. There is a pause. Finally ANDREW goes on, awkwardly, attempting to speak casually) Uncle says you’ll be gone three years.

ROBERT: About that, he figures.

ANDREW: (moodily) That’s a long time.

ROBERT: Not so long when you come to consider it. You know the Sunda sails around the Horn for Yokohama first, and that’s a long voyage on a sailing ship; and if we go to any of the other places Uncle mentions—India, or Australia, or South Africa, or South America—they’ll be long voyages, too.

ANDREW: You can have all those foreign parts for all of me. (After a pause) Ma’s going to miss you a lot, Rob.

ROBERT: Yes—and I’ll miss her.

ANDREW: And Pa ain’t feeling none too happy to have you go—though he’s been trying not to show it.

ROBERT: I can see how he feels.

ANDREW: And you can bet that I’m not giving any cheers about it. (He puts one hand on the fence near ROBERT).

ROBERT: (putting one hand on top of ANDREW’S with a gesture almost of shyness) I know that, too, Andy.

ANDREW: I’ll miss you as much as anybody, I guess. You see, you and I ain’t like most brothers—always fighting and separated a lot of the time, while we’ve always been together—just the two of us. It’s different with us. That’s why it hits so hard, I guess.

ROBERT: (with feeling) It’s just as hard for me, Andy—believe that! I hate to leave you and the old folks—but—I feel I’ve got to. There’s something calling me—— (He points to the horizon) Oh, I can’t just explain it to you, Andy.

ANDREW: No need to, Rob. (Angry at himself) You want to go—that’s all there is to it; and I wouldn’t have you miss this chance for the world.

ROBERT: It’s fine of you to feel that way, Andy.

ANDREW: Huh! I’d be a terrible brother if I didn’t, wouldn’t I? When I know how you need this sea trip to make a new man of you—in the body, I mean—and give you your full health back.
