The third point of view:
The tension in the room was so great that the triple trouble had an illusion of gasping for breath. After the "trouble" they caused at the bouquet, they had been confined to their parent's room, never to leave until they returned. And now, their parents were back, they craved for an escape because Niklaus was frightening right now.
Niklaus hadn't made a move since he returned, rather he treated them with silence. And that silence was the most uncomfortable feeling in the world because they couldn't tell what he was thinking.
Their mother had left for fresh air but the kids understood that signal - she was leaving the discipline for their father. They had to deal with the more stringent parent.
Allen was the first to break the silence, he couldn't stand it anymore, "We didn't mean to disrupt the bouquet -"
"But you did already," Niklaus tone was harsh.
"We were sure of -".
