@WhiteChocolateLover, the reason I said that for Topher is he had pretty much the exact same plot for 6 episodes ("I want to be like Chris"), up until he gets Chris' phone where it's the first time he does something different.

It was never made clear whether he loved or hated Chris early on, but what was clear and has remained consistent is, he wants to be Chris. That has never changed from episode 1, and the only reason he was different in the final 2 episodes was because he got a new opportunity to try take Chris' job. Unlike Sierra who saw Chris for who he actually is and rejected him, Topher knows Chris' true nature and still doesn't care.

As for Scarlett, I wouldn't really say she developed either. But at least she didn't do the exact same thing for 6 episodes. Alejandro definitely developed, he originally had a stone cold heart devoid of empathy, but he softens up for Heather and accepts that he loves her.
