Good catch! That was a stupid one, I simply forgot to add a trigger (condition) in Mr. Rat's dialogue. I fixed it already as this was way less complex than what you reported for Southern Edge and took like 2 minutes... Those in SE will require a bit more than that + I will require an actual test. 

As for the man in red:

it's not the same man as the one from the graveyard quest. It just uses the same shirt color. The man in red from this mod is somewhere in the Bridge's Block. HOWEVER, those rooms are darker than the outdoor areas red won't be as bright, probably with darkish light, it may be a bit red-brown.
