It always felt like Grevioux wanted to write Dwayne but wasn't able to since Dwayne was dead--so he revamped and retconned Bandit into being Dwayne-2.0. None of what he wrote with Bandit rang true to what had previously been established about the character. There were references to a shared history that never actually happened, a brotherly love and affection that never actually existed, etc.
The most offensive part was having Bandit berate Silhouette for having "betrayed" Dwayne...never mind the fact that Dwayne and Sil were already broken up before Sil even met Bandit, so she certainly was not cheating on him, and Bandit was the one who pursued her specifically to hurt Dwayne. So, really, which one of them is the "betrayer" there?
If Grevioux had actually been able to use Dwayne, that series may have worked a lot better than it did. But his attempts to force Bandit into becoming Dwayne-lite just made a mess of it.
