He and she both know the rule, the only rule—they cannot interfere with whether a mortal lives or dies—but it is almost impossible to obey as they watch the dropship fall.
"Please," she whispers.
"They will make it," he replies. "They have to."
Both he and she both sigh in relief (out of habit, not necessity, as they no longer need air where they are) when the children unbuckle their seats, unharmed. The two of them look at each other thoughtfully as the short blonde girl and tall brown-haired boy argue in front of the dropship door.
"The air will be fine, Clarke," he whispers fondly, knowingly. He, and she, have seen the Grounders, seen the Mountain Men, seen all of what is on the ground. It is almost harder knowing what is in store for these kids than being unaware like them. The air should be the least of their worries.
She cries when the boy hugs his sister. Later, a sad smile appears on her face at the wild look in the brunette girl's eyes, at her uncontrollable energy and exuberance. She is happy the girl is finally free but knows that innocence will get her into trouble on the ground. "Be safe, please," she murmurs as the girl jumps into the water.
When the monster comes, she turns away, not being able to watch the girl in danger. She only turns when he whispers, "They saved her. She's alright."
Alright is a relative term, she realizes, when she sees the wound on the girl's leg, when she watches the girl hobble painfully through the forest pursued by Grounders.
He curses when the blonde turns around, intending to go back to save her injured friend after hearing the desperate scream. "Later," he pleads. "Get him later, when you're safe." The spacewalker has the same thought, and he thinks he could grow to like this boy.
He watches with a grim face and she with a disappointed gaze as the brown-haired boy turns the crowd against the blonde. He smiles and she shakes her head when the blonde calls the brown-haired boy afraid. His smile grows bigger and she rolls her eyes when the boy needles the blonde: brave princess. The two of them look at each other in frustration as these two strong mortals clash with one another in world already filled with too much conflict. This cannot continue, they know.
"They're both just scared," she says.
"They should be," he replies.
Later, the two of them know what fear is when they watch the blonde dangle over the pit, her only anchor being the brown-haired boy's hand.
"He won't drop her," she says, but the boy is taking too long to pull the girl up and she cannot stand idly by anymore.
She closes her eyes, sinking through the floor until she is next to the brown-haired boy and it is all she can do not to reach out and brush the curls from around his ear. Instead, she leans in and whispers his name: Bellamy.
That is all it takes, her voice in the boy's ear, for him to tug the blonde up from danger.
When she returns, he looks at her in surprise, his raised eyebrow asking if she thinks she is above the rules.
"I was never much for rules," she says, one hand drifting towards her stomach.
Surprising her, he grins. "Neither was I."
