I loved the lines about their cousin, who’s a bit thick and smashing the beetles. Because it was about something from their past. It’s like Tyrion’s in shock, or something. He doesn’t know why he’s telling that story and he just wants to know what it was about, and what life is about, and it had such an abstract non-f*****g King’s Landing feel to it.
What the actor didn't say is that there may be a big reason the scene had a “non-f*****g King’s Landing feel to it”: it’s possibly a major diss in disguise.
