She asks Tommy to steal his father's necklace, so she will look like she told the truth to her friend, offering to introduce Samantha to Chuckie in return. Tommy plans to ask Stu if he can borrow the necklace for the night, but quickly realizes it is easier said than done when Stu says he cannot dance without it. Tommy makes a fake necklace by wrapping a round dog biscuit in gold foil with the zodiac sign drawing and switches it out for the real necklace. Unexpectedly, the now old and overweight Spike eats the decoy overnight, then mistakes the real necklace for another one and takes it. Stu finds out the next morning, and Tommy takes the blame for stealing it. Upset and reluctant to do so, Stu and Didi ground Tommy from attending the Emica concert, much to Dil's dismay, and because of this, Angelica refuses to introduce Chuckie to Samantha. Stu and Didi hire Susie to babysit Tommy while they are at the dance, as she is unable to attend the Emica concert. Lil finds the necklace in the sandbox, as Spike buried it there once he discovered it was not a dog biscuit like the decoy was, and the gang convince a reluctant Tommy to come with them to return the necklace to Stu. Susie (who is watching the same sci-fi film as the babies did at the beginning of the episode) catches them as they leave the house, stating that she knows when they are always up to something. She then eagerly goes with the gang to return the necklace. On the way, they ride their bikes by the concert, where Angelica, who is nervously facing peer pressure from Samantha, runs towards them to get the necklace. Tommy confronts Angelica and tells her that he cannot give her the necklace because he should not have agreed to their deal and that she should have introduced Samantha to Chuckie in the first place, and urges her to tell the truth. Wanting the necklace but ultimately feeling remorse, Angelica admits to Samantha that the necklace belonged to Tommy's dad and also reveals that she and Tommy are cousins. As a way to try to make up, she introduces Chuckie to Samantha as "Charlie Finster, III". Samantha shares her experiences with braces to Chuckie as he is wearing them also, and the two are smitten with each other.
