Spotted one last night, watching that episode where AJ loses his eyebrows. At the start of the episode, Tony is wearing a really wacky shirt.
Carmela is upset that Tony is indulging AJ, and she resents being forced to play "prison warden" with the kid. Throughout the episode, Tony is doing things like buying the kid a bright yellow SUV while he supposed to be studying with his tutor, while Carm is one who has to say no, you can't go to a concert and stay overnight in a hotel in the city.
Carm tries a few different approaches to get the kid to stop hating her, but he's not having any of it. Distraught,she finally relents and gives permission for the concert (but no hotel, he can stay at Meadow's instead).
The subtle moment: in the scene where she gives permission, she's wearing a tan shirt with horizontal black stripes on half the front, and vertical stripes on the other half, recalling the shirt we saw indulgent Tony wearing back in the first scene (sorry, can't find a pic of this one).
