I'm going to keep this short.

The fans wants Emily Quartermaine back.

This copy called Rebecca is not going to work.

So please make Rebecca, Emily.

How?
It's a soap. Everyone dies, and then comes back to life atleast once, Now it's Emily's turn.
Helena kidnaped her, and brainwashed her to believe she is Rebecca.

So many possibilities.

(PS: when Emily is back. Please give us a Nik/Em baby! We've been waiting forever for a Cassadine/Q baby :) )
