I am Sam, the chameleon, shapeshifter and actor.
You already know them more than you think as they have been impersonating others in the system for a while now.
Though if I don't trust you don't expect me to actually introduce myself if I am around, I am way more likely to just stick to the role of the person who was there before me.
If you have a problem with that then you can contact Rose for kneecap removal.
