Zero was excited. The pieces were finally all gathered. All he had to do was assemble them. Understanding the relationship between different types of energy and the true purpose of chaos energy made Zero more confident. If his hypothesis was correct, Solo would be able to manipulate chaos energy. After all, he was trapped by chaos energy for a long time, most likely a deliberate set up by his past self.
Firstly, he had to find a way to create a defence against chaos energy. Zero didn't tell Merlin what he was doing and snuck out to Titan's Cliff alone using the portal from the lamp. After learning how to modify portals, Zero found that this ability was extremely handy. Mii and Wii seemed to have levelled up too from all the new knowledge.
