Earlier tonight we saw Game of Thrones Season 4 Episode 1: "Two Swords" — and in the process, we met Oberyn Martell (Pedro Pascal). We haven't seen enough of him to get a solid read, but there are some things we know for sure about the Martell second son: He loves having sex with women, he loves having sex with men, he loves doing both of the former with his paramour Ellaria Sand (Indira Varma), and he hates House Lannister.

In the course of… oh, about five minutes, we saw the Red Viper let his not-a-lady pick out a girl at the brothel, throw around his prince title to get in a brothel employee's pants ("I'm a Prince, boy! Have you ever been with a prince?"), and stick his dagger right into the wrist of some lesser Lannister.

He's witty, but kind of skeezy. He's honest, but also brutal. And we're not 100% sure if we're on his side or not.

Some little moments immediately endeared us to him — for example, his speech before stabbing "so many veins" in that Lannister wrist. "You know why all the world hates a Lannister? You think your gold and your lions and gold lions make you better than everyone," he said. "May I tell you a secret? You're not a golden lion. You're just a pink little man who is far too slow on the draw."

He may be vengeful, but he has good reason to be. He hasn't been the first character to hold a grudge over the rape and murder of his sister, Elia Targaryen (nee Martell), and the brutal murder of her children — but none are quite so mad about it as Oberyn. "The Lannisters aren't the only ones who pay their debts," he told Tyrion Lannister (Peter Dinklage) after recounting the story.

As noble of a reason he has to be permanently angry, though, he could be a threat to people we actually like — like Tyrion, and even Sansa Stark (Sophie Turner), who's technically a Lannister now, too.

What do you think? Is he a refreshing new face on the series, or does he make you super-nervous? Vote in our poll below, and let us know your thoughts in the comments!`
