Then please explain why you are suddenly so eager to defend another player? First, you tried your best to cast doubt on the solution to the clue, and then you attempted to shift the blame onto me by somehow linking the clue to me. Even if we assume you are an investigator, after just one night, you cannot possibly know a player's attitude towards one side or the other.

I'm not defending anyone, and certainly not "with all my might." Menti, by the way, also noticed that the solution isn't a perfect fit, although I'm not denying that it could be correct.
And yes, I'm not shifting the blame onto anyone; I'm just sharing what I found, which is better than nothing. You suggested your version, I'm suggesting mine; someone else might suggest something else, and it might be useful later.

And yes, you didn't answer about the connection between the song and the Lannisters.

There can be many different connections found here; it's roughly like "Heroes 5 - Railag" or "Heroes 5 - Elves/Humans/Demons, etc.," to make it clearer. I haven't read all the books myself, and it's been a while, so I don't remember everything; I'm not a big fan.
