Talk:'Til Death Do Us Part/@comment-25241238-20170617023537

I thought for a while that maybe Spencer has a twin, and the twin could be A.D., but the more I think about it, wouldn't Mary Drake and Peter know she gave birth to two babies? Why would he only keep Spencer and give the other one up for adoption? I know it's PLL world but still it doesn't make sense, Mary Drake would've said something.

At this point it makes more sense to me Spencer having a personality disorder than having a twin.
