I also found the whole thing distressing & difficult to see and as a previous post mentioned I think the level of fear & helplessness she showed made the whole thing feel alot more sinister than a regular domestic, not to mention the lack of remorse & guilt he showed after making it apparent it could worsen or happen again in time.
I would be very disappointed & surprised if RLC do nothing at all, they cannot control what happens in the apartments however now they are aware the incident happened they have a duty of care to at least offer some assistance or make sure she is safe and happy to continue performing on the site.
Personally I now have no desire to watch them as a couple at all, although she's done nothing wrong .... it's going to be very hard to shake the abuser & victim image.
