Hayden Donnell (has memorised every word of every book and spends his evenings correcting historical inaccuracies on the Westeros Wikipedia page):
Tywin Lannister can skin a deer while delivering a lecture on the intricacies of politics. He ended a war with some skilful letter writing, then sewed up half the Realm by marrying two of his children to a weeping northern teenager and a "renowned pillow biter". Before Tyrion told the assorted nobility of King's Landing he'd love to poison them all, Twyin was in the middle of a masterclass in how to make the most out of the murder of your sociopathic grandson. Even Jaimie's last ditch attempt to save his brother had been worked into his schemes. That look in his eye when his son defied him and demanded a trial by combat may have been the first time he has ever been genuinely surprised. He looked like the Wolf of Wall Street did before he stormed off the set of 60 Minutes. Tyrion may be the only person in King's Landing with a mind to match Tywin's. It's the older Lannister's greatest weakness that he can't see it. He's blinded so much by Tyrion's height that he can't appreciate his mind. That makes Tyrion, even in shackles, his greatest threat.

Peter Dinklage has been Game Of Thrones' not-so-secret weapon since the first episode - in the hands of lesser actors, Tyrion Lannister could just be a happy joke, but Dinklage has spent the last four seasons filling the character with real depth and humanity. This was highlighted once again in this week's episode, as Tyrion sits in resignation and frustration, and listens to the world calling for his head, before taking charge of his own destiny. The moment of final betrayal, where the one person he thought he could still trust - and even love - turns on him, like all the rest, is heartbreaking, especially when Tyrion begs her to stop. But then he lets fly with a vitriolic tirade that has been building his entire life, finally spitting out truths that others would rather not hear. He's still facing the sharp edge of the executioner's sword, but Dinklage shows that an imp with nothing to lose can still be triumphant, and scare the hell out his awful Dad.
Bridget Jones (a latecomer, but only because she is incredibly impatient and prefers binge-watching. She'll look at spoilers, but will always deny it):
First things first. If someone kills Tryion in this "battle to the death/innocence" palaver, I don't think I can continue watching this thing. Peter Dinklage is the best at everything in the whole world, and that is the end of it. Second things second. Daenerys needs to get that Three Day Nanny in from TV3 and sort out those scaly kids of hers. Now I don't have children, but I'd like to think that if I did, (and if somehow my offspring were, ah, dragons) I'd be able to teach them that burning people's stuff - especially when that stuff is a herd of cute goats - is really quite wrong. Danny, all the money won't bring back those sweet little goaty faces. And as the nanny lady said on her show last week, your children need to respect you, otherwise they will turn into out-of-control lunatics who, in all likelihood, could burn the entire world to a crisp and ruin everything. It was something along those lines, anyway.
