Sceleritas Fel, yes yes little imp butler, wretched little thing.
Rose didn't toss him aside like he was useless (as irritating as he may have been), but she DID utilize his servitude to the fullest she could.
Sceleritas Fel was entrusted to Rose so he may guide her and serve her. He took pride in doing well.
She didn't mind that he also answered to Bhaal. They both answered to Bhaal. Finding a way to work together, happily, only worked in their favor.
She knew she could rely on him to encourage her urges, offer advice if asked. Not once did she think to hide things from him.
In a twisted sort of way, they could've been considered friends.
But then she stopped asking for his assistance. She was keeping secrets-- from everyone, but he didn't care about everyone-- she was keeping secrets from him. And it all started when she and that filthy banite started working more closely together.
Rose said it was all professional, that whatever sins of the flesh she enjoyed was merely that, enjoyment. Same she she did with her Bhaalists. Sceleritas believed her.
But something didn't feel right, and he couldn't shake that feeling.
And when he found her, she wasn't the same. She wasn't her.
His Lady, His Wretched Majesty.
Gone. And she wasn't coming back.
