The Third Olsen Sister: Elizabeth Olsen

Who knew there's a third Olsen sister?  Well maybe "The Onion" did. I know your initial response might be this,  but there is.

 Elizabeth Olsen is the younger sister of Ashley and Mary-Kate Olsen.  Like them, she's an actress.

The appearance of a third sister seems pretty suspicious to me though.  How come we're just hearing about this sister now, and why didn't anybody mention her before?  It's sketchy that all of a suddenly she shows up.

Also, Elizabeth doesn't really look anything like her sisters.  Instead, she bares a striking resemble to Vera Farmiga.

That's certainly not a bad thing, unless you're Farmiga and there's a younger version of yourself.

Elizabeth Olsen

There has to be an explanation for all this.  Elizabeth could be a desperate attempt by the Olsen parents to have a new star since the boat has kind of sailed on the Olsen Twins.

In fact maybe she isn't really a person, but a humanoid robot they created like Vicki from "Small Wonder."

Technology has vastly improved since the 1980s.  Like those indistinguishable Cylon robots in "Battlestar Galactica" or the Buffy Bot from "Buffy the Vampire Slayer."

By the way, the son on "Small Wonder" must have had one messed up childhood.  He has a sister, but it isn't really his sister because it's a robot.  Then he develops robot attachment issues.  I don't even want to think about his confusing adolescence.

Or maybe Elizabeth is a clone of some sort.  These are all legitimate answers... at least according to sci-fi television shows and that's good enough for me.
