If you didn't think that Petyr Baelish was the most evil character in Westeros before, then this week's episode of Game of Thrones — "Mockingbird" — gives you pretty concrete proof.

The most interesting part of this week's episode happen in the Eyrie during the last 10 minutes. We see Sansa taking solace in building a miniature Winterfell in the snow. Sansa has hit rock bottom at this point. She's far from home, thinks her entire family is dead, and is now betrothed to the most annoying kid in the Seven Kingdoms.

Oh, also a creep that just talked about how hot her mom was tried to kiss her.

Lysa's horrific death through the Moon Door after confronting Sansa about the kiss was something we all saw coming. She was painted as an unsympathetic character — an ugly, jealous hag whose love made her blind to reality. Her death was shocking, but not because anyone would miss her. Lysa really is one of the weirdest characters in the series; the product of living in the shadow of her older sister and having to marry a man several times her age for family duty.

While Sansa's situation looked bad before Lysa's death, stuck in a horrible place and potentially engaged to someone far worse than Tyrion, it might be worse now. Petyr doesn't seem concerned about age of consent, and his obsession with Catelyn Stark means Sansa might be stuck in future awkward situations. Or he could take her under his wing as the future super-manipulator of Westeros.

While we haven't learned how Petyr plans to explain how Lysa fell down a giant hole in the floor, it's clear he'll be able to explain his way around it. Petyr is now the ruler of the Eyrie and its lands, but his thirst for power probably isn't going to stop there.

If Lysa's death was the episode's biggest surprise, the stalling before the trial by combat was its biggest disappointment. But at least we got a lot of great Tyrion screen time in the meantime.

Tyrion learns who his few remaining allies are and aren't as they come to visit him in the Black Cells. First it's Jaime, who wants to chide him for not accepting a deal at the wall. But as Tyrion points out, that would have given Tywin everything he wanted: his favorite son would have to go to Casterly Rock and father kids legitimately, and the son he hates would be banished to a snowy hellhole forever.

Sadly, Jaime explains that he cannot defend Tyrion in battle.

Calling on Bronn turns out to be just as unsuccessful, as the sellsword has done what he does best: do something for money. His point that he can't go up against the Mountain — Cercei's choice for Tyrion's trial by combat — is a fair one. It's just a shame to see one of the show's best characters go out by getting married.

In the hour of need, Tyrion receives a visit from the Prince of Dorne, who continues to be one of the coolest characters of Season 4. From this visit, we learn how long Cercei has held a grudge against her brother: from the time he killed their mother coming out of the womb.

Unfortunately, we're forced to wait two weeks to see the battle between the men known as the Viper and the Mountain. It will definitely be worth it.
