Dreamer figured that the Demons were the one who took the three Rings and since Tesla couldn't hear Helix, he didn't believe Dreamer.
Dreamer then told him everything that Helix said and Tesla finally saw the point.
"I can understand why Helios collected the rings before you, but why did the Demons do the same? I mean, how did they get to know that you were collecting the other Rings?"
"You heard him, Helix. Got anything to say?" Dreamer asked.
Helix paused for a moment before replying.
'You won't like the answer.'
"What? Wh-Why?"
'Listen, Helios hates you. So, when he figured out your plan of collecting the other Rings, he moved first and collected the other Rings to spite you, to make you annoyed. And I am sure the Demons have done that for the same reason as well. Both Gods and Demons want to annoy you.
Helios wanted to win against you so he thought if he collected the Rings before you, it would be his victory.
