It is a very sweet scene; so sweet, in fact, that Ashley's numerous death threats should anything go wrong are more than discounted by the sunny, grateful, honest smile and understanding that Caleb shoots back.
Alternately: It is a very sweet scene, which means a station wagon is about to hop a curb and drive onto the Marin lawn and through their living room and into the kitchen and this car will be driven by Fake Nephew with Ian riding shotgun and the house will explode all around them and A can be like, "Hanna, you still have not suffered enough. I have made a savory pimiento loaf out of the burnt-up charred bits of your mother and boyfriend, with a tomato-based gravy containing your tears. You will eat the entire batch in front of the football team, while your father, his business associates and the school counselor are treated to the video I made of you having sex in the forest last night."
Ezra: "Aria, the fact that you blinded a sexually warped young girl, having set her on fire, only makes me love you more."
Ashley: "Caleb, now that we've adopted you, you can call me by my first name. Mrs. Marin makes me feel so old! You don't think I'm old, do you? Does this ass look old to you? Can I get you a beer?"
Caleb: "Goodnight, Mrs. Ashley."
Ashley: "I'm not like a regular mom, I'm a cool mom!"
Caleb: "I got a good thing going on here. Mysterious Interlocutor, I can no longer play this long con on the Marins. They are too awesome. And permissive.
M.I.: "So all that work we did getting you thrown out of foster care and living in the school and getting discovered by the girls and then getting thrown out of the school and then living in the basement and then living in the forest and now living in the guest room -- all of which, apparently, I was able to predict -- was for naught?"
The cops arrive at Spencer's house due to her totally telling Garrett that she lied to the cops and had means, motive and opportunity to frame Ian for whatever. Her parents are just about dunzo at this point. Melissa -- and people are not believing this, but I do believe this -- explains that the big lie about being in Hilton Head was not because of Alison (whom Ian described as being a creepy stalker that summer) but because he and Melissa were pregnant and about to get an abortion -- for which they needed to drive to an island off South Carolina?! -- but then she miscarried like always happens on TV. Mom's just like, "Spencer, you are going totally SVU on us. You are on a drug called Charlie Sheen."
