On the surface of it, teen murder mystery Pretty Little Liars doesn't have a whole lot in common with HBO fantasy-epic Game of Thrones. But after learning that PLL star Troian Bellisario (Spencer Hastings) was at the GoT Season 3 premiere party we couldn't stop thinking about ways the two disparate shows resonate with each other.

So, in honor of the Game of Thrones Season 3 premiere tonight, here are 10 things these shows actually share. There's a reason we love them both!

1. Girls rule. What's more badass: Dragons and swordplay, or spying and escaping your stalker in three-inch heels? Point being, the young ladies on both shows kick all kinds of butt.

2. Trust. No. One. Rosewood and Westeros are two of the most subterfuge-riddled locations on TV. You have to really know who your friends are, because everyone else is likely to stab you in the back or dig up your darkest secret just in time to blackmail you.

3. "Teams," "Houses" — It's All the Same, Right? Whether we're talking houses bonded by blood or teams of teens bonded by friendship and/or hatred, it all amounts to the same thing: rival factions fighting each other.

4. Huge cast. Game of Thrones gives Pretty Little Liars a run for its money when it comes to major characters disappearing for episodes at a time, and we have a feeling the gaps are going to keep getting bigger. (In the A Song of Ice and Fire book series, three fan favorites go MIA for an entire book.)

5. The past haunts us. The scars of old wars are far from forgotten on Game of Thrones — Robert's Rebellion hangs over the current action almost as strongly as Alison's memory haunts the Liars.

6. Creepy relationships. Game of Thrones, being an HBO show, ups the ick factor to full-on twincest (yes, that is incest between twins), but let us not forget the chilling, apparently non-consensual dalliance between step-siblings Jenna and Toby on PLL. Do. Not. Want.

7. Big twists. We're not sure what shocked us more: The big death at the end of Game of Thrones Season 1 or the revelation that Toby was on the "A" team. Both rank up there as two of the most shocking TV moments from the last several years.

8. No one's hands are clean. Game of Thrones intentionally subverts the High Fantasy paradigm where the heroes are Good with a capital G and the bad guys are just as clearly Evil. Pretty Little Liars also creates a world of greys: the Liars have troubled histories, and even Miss "A" herself, Mona Vanderwall, is layered and sympathetic when she's not being totally batshit crazy.

9. Authority sucks. Government officials are supposed to help you, but Westeros is currently ruled by a sociopathic boy-king, and over in Rosewood, Wilden lives to obstruct justice another day.

10. Hot guys. Not to get all shallow but ... yeah, the eye candy is pretty great on both Game of Thrones and Pretty Little Liars.

Pretty Little Liars Season 4 premieres on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family. And you can catch Game of Thrones tonight at 9 p.m. ET/PT on HBO.
