Why?
A newbie detective contacted me and told me his role. Was I supposed to keep it to myself and work behind the scenes? From a civilian point of view, I couldn't allow myself to be recruited and then whack the D.
So, I was thinking strictly like a civilian and considered all the pros and cons for revealing/not revealing Lemon's identity.
If I didn't go public, there was the chance he gets whacked. Not a big chance, but a chance. Also, if I was whacked, then he was gonna be left on his own. Since he is a newbie who already made a big mistake by contacting me, I feared that he'll keep making mistakes.
In any case, if he's jailed tonight, we get at least 2 more nights from him. If the Gs fail to whack the jailer or the BG, then we will have 4 nights of Lemon investigating.
Overall, I decided that it's for the best the Detective's name to be revealed.
