In the episode "Angela Who?" Angela's brothers convince Angela that she isn't real member of the Anaconda family, because she can do what other family members can't do, or she doesn't like food every other family members likes.

Because of that evidence Angela believes in the words of her brothers and looks for families to which she might belongs to.

At the end Angela ends up in Abatti's Pizza with her best Gina Lash, when Nanette comes into the shop and orders a pizza.

Angela realizes that she and Nanette Manoir have much in cummon so she starts to think that she's a real Manoir.

At first she thinks that a life as a rich Manoir would be great but then thinks about that she'd have to be mean to all of her friends and would have to have ridiculous hairstyles.

After thinking about that she decides to rather be a unreal Anaconda than a real Manoir.

In the last scene you can see that Angelas family picks her up with their car and eats ice cream with Angela.
