Dude, come on.

In all seriousness, thanks. I know a big concern of Twin Charas is 'playing with yourself', but I'm conscious of this, hopefully as evidenced by my immediate splitting of them as the team start to better acquaint themselves with each other. And hopefully I will continue to show Gem and Sia as unique individuals, despite similarities. So far I've gone for a polarised dynamic while sharing similar speech patterns. I'm certainly going to try and avoid tripping into the cliche pitfalls that you've mentioned can come from this sort of character.
