OLTL:What was that promo for wednesdays episode?

I seen Viki/Niki/Jean and I read the thing where it tells you and it says Jean and Viki fight for dominance and then Viki passes out over being exhausted and overwhelmed, So I assume Viki is coming back tomorrow (THANK GOSH I ♥ VIKI!!) but where was she at?!?!?!?!?!?! it was like something was locked I don't know it was like she was in a maze.
