however, i did enjoy the Lord Baelish and Sansa Stark sequences.

To answer your question as to the punchline in Tyrion's monologue, Jamie has it. "I don't know." A bad show would have Tyrion asking Jamie "Why does it have to be this way?". A good show doesn't spell things out as easily, sometimes to the detriment of bloggers, apparently.

Also, if Robin "doth protest too much about going outside", it would mean that Robin actually does want to go outside.

I read the comment below, but still don't get it, unless the whole point is that it's just pointless. Tywin is going to crush Tyrion one way or the other — there is no justice. Is that it?

If so, or not, it was still a long, boring conversation that could have been much better written. No one's gonna win an Emmy for that.

To put it another way: it's like me reading these Game of Thrones recaps written by a brain injured simpleton, seeing them complain about how any bits where the characters talk are "booooring" and mindlessly regurgitate the events of the show we just watched with no insight or commentary, and wondering "why do they do it?" Hearing the horrible noise in my head of them typing out another terrible joke

The beetle speech is not in the books, but the message is. I just don't understand how people who watch the show have not picked up a F!@#$% book yet.
