So it's safe to say Matt became an honorary member of the Nelson family for holidays/vacations during college, but what about Karen? Maybe Foggy and Matt are making plans to spend Christmas dinner with the Nelsons when they realize that Karen just can't grok *wanting* to spend holidays with your family (it's just something you do, not something you enjoy doing) or actually liking the people related to you.

Cue Foggy telling his family he's found another stray to bring home and the Nelsons then Borg-ing her, and love and cookies and Christmas cheer abounding.
