EXACTLY! I understand what the red-blue clue is and why it's highlighted in color! Blue mixed with red gives purple! That's the clue. We're looking for purple profiles and executing them, but I assure you, I didn't kill Hermit. Why would I? I'd rather kill the person I killed yesterday. I don't change my mind easily, and I'm true to myself.
If this isn't a clue, then it simply relates to the theme, as there's a blue team and a red team. But there's really nothing else in the text that fits as a clue

We've talked about the mafia many times, Archie. You know that, given the opportunity, I won't kill you, based on personal affection. There's no need to play to the crowd here.

Just set that aside and try to kill me. After all, you can execute someone during the day.

But will you stab me in the back?

You apparently think I might, since you're suggesting I be executed. Do you want to get rid of me without getting your hands dirty? That doesn't reflect well on you, and it won't make you look any better.
