Pretty Little Liars is like a puzzle, and we're always looking for any clue-sized piece to fill in the picture. What better source of info than the promos for each new episode? A close look often reveals potential secrets about the next week, which is why we've taken a magnifying glass to the preview of Season 4, Episode 7: "Crash and Burn, Girl!" (July 23).

Here's what we've learned.

What's up with Mike? "Hanna's mom, Emily's parents, and now my brother?" Aria says at the beginning of the promo. "Can it get any worse?" It sounds like "A" is targeting Mike this week. Does "A" try to frame him for destroying Connor's car?

Spencer comforts Hanna. It looks like we can expect a sweet (or maybe heartbreaking scene) of Spencer comforting Hanna, as seen at :04 and :11.

Caleb and Toby team up. Bromance time! These two pretty little boyfriends are working together, as seen at :07. They have a whole map laid out, complete with post-it notes.

Ashley behind bars. It's Ashley Marin's turn to wear the orange jumper. "We know you were set up, but nobody else is buying it," Hanna tells her mom.

A plan. Emily declares they still have time to find another murder suspect, and it looks like that's exactly what the Liars try to do.

A new clue. The promo promises a "game changing clue," and we see the Liars going through someone's kitchen.

A trap? Unfortunately, the promo hints that the clue "becomes a trap," and we see the Liars find a note from "A": "Can't wait to see you at our little barbecue! Kisses - A"

"A" targets Em. Emily gets a note of her own: "You crashed Wilden's. Now I'll make it all come crashing down."

Is Mrs. Fields in danger? At the end of the promo, we see Mrs. Fields in her living room, and then a car crash into said living room, followed by a scream. Will she be hurt?
