Now that Cory and Topanga both know that Shawn and Angela still love each other, they have conflicting views on what to do about it -- especially when, unbeknownst to each other, Cory invites Shawn to join their family Christmas while Topanga invites Angela. Topanga wants to let well enough alone, but Cory misses no opportunity to throw his friends together, but the consequences are not exactly what he wants: after they finally kiss, Angela expresses her love for Shawn, but he protests that he is "not ready" to make the same commitment and she storms off for good. Meanwhile, Eric takes his store Santa job a little too seriously when he convinces Rachel and Jack to help him steal his family's gifts in order to make underprivileged children happy.

While everyone anxiously awaits news about newly born Joshua Matthews, Cory's continued self-absorption alienates Topanga, who now considers herself a member of the Matthews family. Even Eric's little friend Tommy views Joshua as his new "brother." It's only when Shawn returns and is accepted by the elder Matthews as "family" does Cory realize where his true values lie.

Topanga is in wedding plan mode, and persuades (strongarms) Cory into accompanying her, Shawn and Angela to a posh ceremony in the hall of her dreams -- where an unhappy father of the bride offers Cory a million dollars to marry his daughter. Meanwhile, Tommy pleads with a heartbroken Eric to adopt him so he won't have to move to California, and Eric pretends to no longer want Tommy so he can be happy with his new family.
