Does anyone else think this is just dumb:?

I don't know what the writer for AMC was thinking!
Why on earth would they use the actress who portrays Lilly, to also play the part of her HALF sister? I mean, come on, let's get real here, how many times would you see half sister's,who look identical?

Very far stretch, but it seems like they are clawing for story lines. It is awful that they have come up with a character with that personality in the likeness of Lily. I also think it is sad that they wrote Lily of out a what could have been a true love story that could used to show that people, no matter what their ailment is, can find and have true love.
