Okay, season 4. can't wait! Here's a look at Kallus on the base.

Ezra smiles at his evil plan. It was genius. "hey, Kallus. What are you up to?"

The newly minted rebel turns to face him, "I am studying failed rebel strategies. Mon Mothma asked for my advice."

"okay, want some berries?" the boy asks, holding out a bowl. Kallus indicates him to put it down. He leaves it on the table and hides behind a crate. Ezra waited ten minutes before Zeb came by and peeked at Kallus' work. His hand reached down and collected a handful of berries which immediately went in his mouth. It took him a half second to respond. The Lasat spat them out and sped away, looking for water. Ezra burst out laughing then stops to see Kallus smirking at him. The former agent returns to his job and proceeds to eat the fruit. "I knew you were up to something. If you must know, I rather like spicy."

Ezra stalks away, defeated.

So, you want an Ezra x Sabine story? Okay, I see them more as bro and sis but we'll see.
