Explanation

Several days later the weary brothers finally arrived at the ship. Of course, both had agreed wholeheartedly to the taking of baths at the first hotel they had come across, even the human phobic neglecting to grumble about the humans around him. Knives, however, was still upset about the chase, so Vash had been quieter than usual in order not to instil the wrath of his homicidal brother. Besides, the blond still didn't know why his sibling needed him, but knew he must have been desperate to have searched him out.

Vash only broke the silence to tell Knives the insurance girls were visiting Millie's large family for a few weeks, though silently he wondered why he bothered since the cold plant barely acknowledged he had spoken of his friends.

When the ship came into view, Vash marveled at how intact the structure was. He idly wondered if any of the humans had survived the crash, but assumed not as especially since there was no sign a settlement had been created around the base. As he climbed out of the vehicle, his curiosity peeked not for the first time as to why his brother refused to tell him why he needed him. All his sibling had said was a family problem had suddenly arisen that needed to be dealt with.

With those thoughts in mind, Vash silently followed Knives into the ship.

Quickly walking through the interior of the ship without a single word, Knives stopped when they reached the arboretum. Searching to see if the abomination had destroyed the environment, he was surprised to find everything was as he had left it but brushed the emotion as merely not enough time for the filth to have destroyed anything. Looking for the female, he did not see her anywhere and knew there was only one other place she could be.

Ignoring Vash's cry of amazement at the sight of the lush environment, Knives briskly walked in the direction of the plant room. When he entered, he found the filth leaning against the center bulb and obviously communicating with the angel. Opening his mind in an instant, he rejoiced at being able to hear their conversation as his sister appeared to be openly speaking.

"Why does he have to be so disagreeable all the time?" Knives heard the female say, gritting his teeth as he realized the abomination was speaking of him. "I mean, I didn't ask for this gift but he acts like it's all my fault." The disobedient manner her tone showed raised his ire further and he realized he would have to remedy that bad habit quickly, with or without his sibling's assistance.

"He has wounds that he can not heal by himself." Knives heard the angel respond gently, apparently trying to curb the female's dislike. "That is why you must be strong and break through his emotional barriers, child." Then the plant suddenly stopped and looked in Knives' direction, her brightened face turning downward slightly. Erica, wondering what the angel was staring at, also turned and saw that the insane plant had returned.

Rising and brushing herself off, Erica calmly walked down the platform toward the door. She expected him to ignore her or give her a command, but instead he grabbed her by the arm.

"Do not speak of me in such a manner ever again, abomination" he ordered, voice barely above a whisper. "If you do, I will be forced to use other, more persuasive methods." Knives tightened his hold to emphasize his threat, grinning with a slight madness on the corners of his mouth.

Erica trembled unconsciously, momentarily unsure if he would abide by the plants' wishes not to harm her.

At that moment was when Vash decided to step into the room. Seeing his brother holding someone who appeared to be girl, and a very cute girl to boot, he quickly raced up the platform and wrenched her from his brother's grasp.

"Knives, what do you think you're doing?" he asked, pushing the girl behind him in a protective manner. "That's no way to treat a lady!"

Suddenly, it dawned on Vash that there was a human girl staying in his brother's home. His mouth slowly formed into a smile as he looked back and forth between Knives and the girl, his eyes gleaming mischievously.

"Um, Knives?" he questioned with an innocent tone. "What are you doing with this pretty young lady in your ship?"

"Vash, get your mind out of the gutter!" Knives order, sensing the insinuating tone and mentally gagging. "This...this abomination is only here because the plants do not want her to leave."

With those words Vash was now truly perplexed. This girl was here because the plants specifically wished for her to be here? Obviously they were going against Knives' wishes, since the total annihilation of all mankind was his only purpose in life. He couldn't fathom what special attachment the angels had to this girl, but it had to have been strong to force his brother to keep her here.

"Knives, I think you have some explaining to do."
