[spoilers] Janus Slynt

Have you ever wondered wether John Snow and Tyrion Lannister talked about Lord Janus Slynt?

Like after the war or on the to Kingslanding: Tyrion be like: What happened to that slimy Slynt after I send him to you?

And Jon: Oh, I beheaded him on my second day as Lord Commander.

Made me chuckle, as I am on my 10 rewatch at this point.
