So, first thoughts on episode 1 then? I thought it was GREAT. The bit where the sisters met each other was really creepy, and I was really terrified the whole way through.

It took me a while to work out not everyone died in the bus crash, and that Simon and Mrs Costa had been away for much longer.

I know it was an artistic device really, but that butterfly must have been super-strong to break through the glass. Do the other returners have any sort of super powers?

Is the water level in the dam going down because all the years of dead bodies are climbing out of it?
