I never know what to think of Tyrion. I get the impression he will be around for a long time in this series, but it's as easy to expect him to get killed at some point, depending on how being a Lannister and being an imp balances out (well, at least that seems to be Tywin's dilemma concerning him).
I don't really care much for stuff related to Melisandre at all. Well, at least before I started reading the books and paid attention, but I haven't read very far. I really want to keep reading, since I'm still in the middle of Book 2, but school starts again soon so I don't think I'll be able to make good progress reading. I should go sit in a coffee shop and read all day sometime this week.
On a separate note, I watched Series 2 of Doctor Who last week. I'm excited to see some new companions.
