I have to laugh.
According to Spence Diamonds, and Fiona, the mysterious Sarah is now touring Japan, as we learn that Sarah somehow knows Fiona, despite the fact that the annoying Scottish sister appeared on the scene after Sarah had left Spence for some unknown travels.
But wait.
Apparently Sarah is not in Japan, she is actually answering the phone and taking orders at 1 800 GOT JUNK.
In Toronto.
Apparently Sarah exists in two parallel universes.
I know it's all silly fiction, but geez, at least try to make sense.
