AN: At present I'm working on a multi-chapter fic which delves into Kallus' growth from season 3's finale up to the finale of season 4. As I was writing, though, I thought back to Yularen and his' interaction in "Through Imperial Eyes", and I just had to get this out of me before I could continue on the main project.

Short as it is, I hope you enjoy!

I Keep Tabs On All My Star Pupils

or...

"Yularen's Mad At Kallus But Also Kinda Sorta Proud"

"Colonel Yularen!" Kallus can't keep the surprise from his voice. The colonel turns, and smiles in tender recognition. "I don't know if you remember me from the academy..."

"Of course." The voice is warm and distinct in Kallus' ears, and for a moment, he forgets he's a rebel. He shakes the man's hand, and his heart swells with unabashed pride. "Young agent Kallus. I keeps tabs on all my star pupils."

Wullf Yularen is a man in the empire who cares. A man Kallus had wanted to be. A man Kallus had admired beyond anyone else. A man Kallus had believed in. He is happy to see such a man again. "What brings you to Lothal?"

It is Thrawn who answers, and Kallus remembers who he is now. The new man he wants to be.

Fulcrum's heart tremors with fear.

"Because, Colonel Yularen, Kallus is the rebel spy. Fulcrum."

He does not believe it, at first, because he doesn't want to. Then Thrawn explains until he's forced to believe it, because it's true.

"I would have never suspected one of my best students...was capable of this betrayal."

But he can, he realizes, because his best students were never droids or pawns to be used. They were people with minds and thoughts and wills of their own (and they were good people).

His heart aches. He had, at one point, been fond of the young man, as a father was fond of a son. But Fulcrum (and Thrawn, too, a voice supplies) had taken that away.

...Yet, still, he's proud. Kallus had been one of the empire's greatest agents. Now, he's the rebellions best agent.

Kallus had betrayed his fondness, but he would never betray his teachings, and for that, Yularen is grateful.
