Thought last night when Kathy claimed to Phil nobody would recognise her somebody would. Maybe they did but we just didn't see who on camera. The one that would perhaps have made perfect sense would be Marcus Christie. Anyone else would probably have ran after the car immediately but Marcus wouldn't be beyond using it for extortion perhaps? Know there's only so much space to fill but perhaps the thought did occur to them. At least enough to tease it by showing Kathy then cutting to Marcus coming out the back yard.

I thought Jane was going to see her at first. She'd recognise her from photos.

That would have been a great twist.

I thought it was quite weird how Kathy thought no one would recognise her and just sat casually She only had to wait a few minutes until they were off the square

I thought she would be spotted

I'm surprised she wasn't. Definitely thought Jane was going to see and recognise her from photos but then dismiss it as impossible because she's meant to be dead

Of course there's no reason why Marcus would actually know she's "dead" but they would probably overlook that.
