"There is a bounty on his head, and Arya Stark's name is sure to demand they take her from his custody."
The bounty is from the Lannisters, who have no open friends there at all. So who cares? It only makes him MORE likeable, since the bounty is from their enemy... but they might expect him a spy. Except that he already gave his name from the start...
"Tyrion saves the beetle he picks up in his cell."
Actually it's a Woodlouse, (Oniscidea) which is a crustacian.
On the "dropped" cousin. I'd chalk it up to human baser instincts to kill animals for food, and sometimes hunt for sport.
Destruction is in man's nature too...
"(There's also a funny bit with Tywin cutting off the officious speech from Maester Pycelle.)"
Yeah, that made me lol! Maybe the old geezer will get revenge one day, but I hate him so nice to see him humiliated.
"The gruesomeness of Clegane popping open Oberyn's skull like a can of beer is possibly one of the most terrible things I've ever seen on TV."
Really? Nothing special imho... But without doubt it was AWESOME!!! The whole fight... and then his extremely sudden downfall so VERY fast. WHOA!!!! Definitely going to be talked about for a LONG time!
"I reminded her what will be happen politically now that the Prince of Dorne has been killed in the capitol."
He went there for revenge, *agreed* (very eagerly) to a one on one duel to the death and then his obsession made him careless and dead.
EVERYONE saw it happen. So what are they going to complain about? Not like it was an evil plot or poisoned sword.
That leaves me with your comment about what was being waxed on the spears... Intrigueing!
