Well. Cad, like Boba, has a sense of honor. That was proven when he saved the disguise Obi-Wan Kenobi in the Box. He's smart and resourceful. But unlike Boba, he vies for the top position. He isn't just there, and there are none better than him, like Boba. Embo is a challenge as far as that goes, for sure.
I have to say, I really like the character of Cad Bane. Even now that we're going into Season 5. But I doubt we'll see too much of him /or/ Boba in this season, sadly.
