On episode 21 (Another Zatch), Zatch remembers who erased his memories, Zeno, and tells it to Kiyo.
Where Zatch really, really, really meets Zeno was in a sub:
From Episode 147 (Reversed future. Thunder emperor Zeon. Prelude to ruin)
Episode 148 (Raging Zeon! Two fates. Gash's secret)
Episode 149 (The inheritor of Baou. Gash vs. Zeon. Jigadirasu's thunder)
To Episode 150 (Decisive battle against Faudo! The golden radiance. The kind king)
Zatch is Gash in Japanese
Zeno is Zeon in Japanese
Zatch really doesn't meet in dubs exception episode 21 where Zeno makes his first appearance except for the time where Robnos mentioned he saw someone from England that looked exactly like Zatch on Episode 16 ( The Invulnerable Robnos) however, Robnos didn't gave any other information about this "Look alike" (Zeno).
Except for the episodes I just showed you, Zeno also had a flashback where he destroyed Rops' book, it was on episode 42 (Coldhearted Foes)
Hope I helped!

SPOILER ALERT!!! SPOILER ALERT!!!All of this information is from the manga. I am not sure if the anime holds the same answer. This answer also might contain spoilers.Zeno Bell hates Zatch Bell because his father (who was the King of the Momodo World during that time) gave Zatch the Bao Zakerga (or how ever you spell it) instead of Zeno, which is later revealed to be Zatch's older brother. So why did the Momodo King give Zatch such a powerful spell? The answer is because Bao is very dangerous. Bao Zakerga ate sorrowful and evil souls and thoughts. It was a super powerful spell that helped the King get his throne. Their father new that Zeno has a blood lust just like himself, and Bao could easily devour Zeno if he did not control it. So the father sent Zatch Bell after giving him the Bao right after birth, hoping for him to control his power in the far future, to the countryside where nobody would know Zatch's true identity. Not even Zeno. The father, of course, did not want Zeno to know about his younger brother because if he knew, he would chase after his brother and destroy his to obtain Bao himself. I should add that Zeno had to go through harsh training because he was known as the Momodo King's son and had high expectations while Zatch had a relaxing life in the countryside (later Zeno gives Zatch's memories back and... yes, Zatch's memories were stolen by Zeno... and finds that Zatch had a pretty harsh life in the momodo world: emotional and physical). Zeno later finds out about Zatch and Bao Zakerga being given to him. He get angry at his father because Zatch obtained Bao without an effort at all and has a relaxing life while he has to go through painful training...That is my answer. So... yup...
zeno constance is a trinidadian play writter.
