Will Robin's return mean the end of Elizabeth and Jake?
With Kim McCullough (Robin) returning to the show soon (she's already filming), I would say the truth about Jason will be out. Robin will know that Jake is really Jason. Unlike all of Jason's other family and friends, I believe Robin will figure it out quickly. As for Elizabeth, the only choice she has is to say she had no idea who Jake really was. I don't see any other way out for Elizabeth.
I really don't believe Nikolas or Laura will throw Elizabeth under the bus. The only problem is Hayden – if she remembers the truth in the meantime, it's over for Elizabeth. What I should say is, when Hayden admits she remembers who Jake is, it's over. All we can hope is
