Edit: unspoilered as of the air date.
Baxter's fancy restaurant is in a hotel that he owns. Makes sense because nowadays villains own hotels.
It took us five episodes to wander into sterotypical Nawlins, where it is apparently always Mardi Gras, even in mid-late October.
I see we are going the Romeo and Juliet routine with Adam and... Baxter's daughter, who does not get called by name often. I think Adam made a strange, dumb choice here. How did you know Rocco? Oh, from that club that he never went to. Why didn't he just admit that it was morbid curiosity and guilt because Rocco was hit by the car that was stolen from his house? That way it isn't another lie to keep track of it, it's just half of the truth.
As for Michael's mystery stalker, I think we're dealing with a pair here and I predict it's going to end up being Adam's teacher girlfriend and his friend Wesley. The teacher girlfriend knows what happened and I have a sneaking suspicion that if she'll sleep with one student she might just sleep with another. There was also the unusually specific amount of money requested ($220,000) which suggests inside knowledge of how much money the Desiato family might have stashed away. She might have a key to the house. The emergency with the dog wasn't a poisoning, it was just Adam being a general-purpose screwup.
Then again, it might not be them because the proof that was sent to Michael was filmed from directly behind the car. The previouslies show that the gas station footage was shot from overhead. So this means that someone got impatient at the gas pump, whipped out their phone and filmed the person who was taking their time in the hopes that this might turn out to be blackmail material. Sure, why not?
I like the gangster lady in charge of the Desire crew. No messing around with her. She goes right to Baxter, lays out the facts for him and lets him know he's only got so long to respond.
That gas station attendant sure has a phenomenal memory. Sure, you'd remember the sob story and the guy who told it but Gas Station Guy knew the specifics!
