Kanan's Chess Move
We always talk about the fact that Ghost killed Breeze, but we never stop to ask who actually had the most to gain from Breeze's death.
As of Episode 4, we know Breeze believes Kanan is like blood to him. We also saw him set up Taz in what was essentially a "survival of the fittest" test, similar to his fight club philosophy: two walk in, one walks out. My theory is that this wasn't the first time Breeze tested his people, and it definitely wouldn't have been the last.
From everything we've heard throughout the series, young Ghost wasn't just book-smart—he was street-smart too. He had an uncanny ability to disappear, which is supposedly how Breeze gave him the nickname "Ghost." I think Breeze saw far more in Ghost than just another corner boy. He saw a future partner and was beginning to groom him as his number two, just like we're seeing him start to take a liking to Kanan now.
One thing Power has always leaned into is history repeating itself. We've seen the parallels between Tariq and Kanan, and even Tommy keeping Diamond in the dark the same way Ghost used to keep Tommy out of the loop.
What if Kanan recognized exactly what Breeze was doing? What if he realized Breeze was slowly replacing him with Ghost and began manipulating Ghost before it was too late?
Ghost wasn't immediately on board. He always said Breeze was like a brother to him, and we know he gave Breeze one last chance. I think that "last chance" was Ghost telling Breeze not to force him and Kanan into competing against each other. Just keep the business running the way it always had.
But Breeze was Breeze. He believed someone always had to lose. He wanted a body on the ground.
That decision sealed his fate.
It gave Kanan exactly the opening he needed to convince Ghost that Breeze had to go. In one move, Kanan kept the organization intact, eliminated the only person who was threatening his position, and held onto his deadliest soldier—Ghost.
