If khaan was the detective, I doubt he'd be so foolish as to reveal himself privately to anyone, since he would be well aware that an innocent night result doesn't mean the target wasn't mafia. I think the math is more like:1+1=2 ?
'khaan investigated Seamus, got an "innocent" result, contacted him through pm, hinting at his detective role and got killed the very next night?
'khaan deduces from this that Seamus is the godfather?
Seamus, can you post the pm 'khaan sent you on that Tuesday?
EDIT: but then again, wouldn't it be smarter for a godfather to keep the detective close to him and alive?
khaan + death = Seamus - evidence
