Wishing her dead feels a bit extreme, but I’d definitely love to see her fall from grace and hit rock bottom. It's not because i hate her but the idea is seriously turning me on.
Well, Kath falling down is one option we have, we simply have to grasp it. One is I doubt Chuck and August will find her plans groovy, so I think an option to talk with them, esp. if we have good relations with the two, will pop up sooner or later. Elias coming in might be the trigger for such a talk with August. Because he is a businessman, shady but still and like all businessmen he highly dislikes disruptions, one which Kath is building up.
The other option is siding with our two doctors, who clearly have their own agenda and warned our hero cryptically that something will happen. In an ironic twist, Abel warned equally cryptical Kath twice, if she is sure to start her powerplay. Kath was sure, so Abel and Sophia are on board too. And with plans going above those made with Kath, the implications clear, since we learned that the official reason they are at the club is nothing more than bogus. They do not need the club for testing Sophia´s new invention, they have "special" labs of their own.
