I call Ava being murdered.
I'm in two minds - either Liam will do it/get done for it
OR
Liam will be a witness and eventually grass them up and be te square hero eventually.
Either way I think they are setting Ava up as resident community hero, ready for a beating/stabbing. It's been a yet since Hev so we are due another death.
That and she's mixing with billy (yeah right) which is the kiss of death IMO.
