Time to sleep it is coming. Palette's dream he was lying in a field full of magical silver flowers illuminated by the light of the full moon, he watched the ocean and the creatures swimming in it.
"Finally, a little freedom..." Nightmare knew that by the time the vial was ready he would be need to tolerate the suffocating amount of attention he was getting. That's why it's good for him to be a little alone, away from the world... "It was enough suffocating already... Lessons with Dream are at least a little bit useful. Maybe I should activate the sect and give Dream a little work to occupy him while I create the double dream world. It won't be easy with this lot of attention..." tiredness slowly overwhelmed him, his consciousness falling asleep inside the dream world. A presence woke him up, Ink came home. Out of bed, he pulled the edge of Ink dress to bring his attention.
– Why are you still awake? You should sleep... – Ink a little surprised.
– I slept! What happened to your paints? – changed the subject Palette.
– Oh! Do you remember what I told you about them? – questioned him.
– They are very important! – Palette replied hesitantly.
– That's right! They are very important! Without them, I would not be able to protect the two of you and the world! – Ink touching his vials with incomplete amounts. – But unfortunately, I can't always be here with you two... – little sad.
– Teach me too! And then you two don't have to worry about me! Because you two will know that I can defend myself! – Palette took the opportunity to drag Ink into to master his power. Ink looked at small Palette in surprise, then smiled.
– All right Palette I'm starting to teach you tomorrow! But now go to sleep! – Ink much happier.
– Okay! – he ran back enthusiastically to his bed. Ink smiled at his enthusiasm. Palette returned to the silver flower field where he practiced the movement needed to fight, hidden behind the disguise of dance.

– Last night after I came home, I talked to Palette – began Ink. – As he did with you, he asked me to teach him how to use his power. As we talked, I became aware of how mature and intelligent Palette is compared to his age... He said he wanted to learn how to use his power so we wouldn't have to worry about him! – he informed Dream.
