We have to admit: we don't trust new girl Sydney on Pretty Little Liars. A newcomer who's all smiles and immediately bonds with one of the Liars? If she's not a love interest for Emily (Shay Mitchell) or Paige (Lindsey Shaw) — and so far it seems like she's not — then our next guess is she has an agenda, and this new sneak peek of Season 5, Episode 4 (“Thrown From the Ride”) doesn't make us any less suspicious

This clip opens with Em and Sydney talking swimming technique; it seems like Sydney has already managed to get Emily to go from offering some friendly advice to basically coaching her. That's strike one. We know it's cynical, but anyone trying that hard to get close to a Liar sets off warning bells for us.

Strike two comes when Em starts to open up a little about how tough it is to be at home these days. Her mom is just bursting with questions about Ali, she explains, and she'd rather be left alone.

"It's kind of natural though, for her to have questions," Sydney suggests. "I would never ask, mind, it doesn't mean I don't have them." She finished the statement with a hopeful little smile.

OK, so she could just be an honest gal trying to bond with her new friend. If this were a different town, we wouldn't give this moment a second thought. But we can't help but wonder if Sydney has less than innocent motivations for wanting to know more about what happened with Ali...

Check it out yourself!
