GoT: heating up

This section of the book is where things start getting interesting. It feels like the author has been building up tension/drama in order to cause a huge explosion of events. Arya while exploring the castle find hidden tunnels and over hears 2 men talking about killing her father, but Arya does not know who the men are and when she tries to tell her father he does not believe her. I really enjoy how her character is set up, unlike the other characters who follow formalities and a "code" she tells it like it is and has no desire to be another housewife (hence the sword fighting lessons). Ned ran into some trouble with Jamie Lannister. This is especially important because now we see tension between the Lannisters and Starks on two fronts (in kingslanding and with Cat). Clearly there is a war about to break out between the two families but thanks to Robert they are holding on by a thread. Tyrion escaped Cat's imprisonment by once again using his wit and money. He also gains a new body guard Bronn who like Tyrion likes money, whore, and is a complete smart ass (so naturally i find him awesome). It will be interesting to see how two men being so hard headed in nature like Tyrion and Bronn will act around each other. I honestly see them as a perfect duo, Tyrion has the brains and money while Bronn is an excellent sword and keeps Tyrions ego in check. Finally, while Bran is riding on his newly saddled horse him and his brother are attacked by wildlings, thus confirms Brans dream where he saw wildlings running south towards the wall leaving us questioning what exactly is beyond the wall? And will the Nights Watch be able to hold them off while their low numbers and weak defenses?
