Now that would be CREEPY! I think it was more of a big sister sort of way in she was older but only by about 10 years or so. Sort of like a sibling that was born later after the first child. Personally, I thought of her as being about college age on the show, around early 20s. It wasn't too far off from her real age of 28. She is like some others, just looks younger than her years. This would make sense because Maggie I thought was around 30 or so.
