Lila agrees to help(with a little buttering up) and training begins, dealing with complementing others, being non-confrontational and telling funny stories.

At the party, Lila is surprised, yet flattered to see that Helga is wearing an exact replica of her dress, Helga sees Arnold by the punch bowl and walks over, Helga tells Arnold a joke and offers him the last finger sandwich.
Later, Helga and Arnold are playing a game of pin the tail on the monkey, when Gerald comes up to have a word with Arnold, Gerald tells Arnold that he is only spending time with Helga because she is dressed as Lila, Arnold disregards this and returns to Helga, but he accidentally calls her Lila, so she decides so take off her costume, and Arnold leaves(possibly confirming Gerald's information) But Helga over hears Lila and Arnold talking, and she hears Arnold say that he comments that he kind of likes Helga, to which Helga sighs that she is half way there.
