Are you desperate to know what's next on Pretty Little Liars Season 4, now that Ashley Marin is under arrest? Us, too. Fortunately, the sneak peeks for Season 4, Episode 7: "Crash and Burn, Girl!" (July 23, 2013) give us a few clues about what's coming up in the episode.

Connor's car is still a question. Creepy Connor's smashed car is the focus of this sneak peek. The culprit is still a question.

Did Mike do it? Mike clearly has less than zero empathy for his former friend's plight, which makes Aria wonder if her brother is the one who got a little smash-happy with Connor's car. Mike denies it, but is he telling the truth?

Hope for Emily's shoulder? In this clip,  Mrs. Fields suggests Ems try prolotherapy, a series of injections that "stimulate the tissues around the injury to promote healing." Could this be the answer to Emily's swimming problems?

Money concerns. That said, Emily seems to be worried the sessions will be too costly, and Mrs. Fields admits that getting the money together for the first session will be "a little tricky." Is it just us, or does that sound like an avenue of attack for "A"?

And what about Hanna? Meanwhile, Em wants to go comfort Hanna, but Mrs. Fields thinks it would be better if she stays away for a while.

Team Caleb and Toby. In this clip, we see Caleb and Toby have teamed up to do some investigating of their own.

Nigel Wright. They appear to have talked to someone named Nigel Wright (that's Jenna's mystery man from Wilden's funeral), and they're thinking he might know more than he's letting on about the night of the lodge fire.

The lighter! In fact, Toby even brings out the lighter with the compass he found the night of the fire. Does "NW" stand for Nigel Wright?
