I think I'm with you on about every point. Tell me Jack doesn't notice that somebody's following him, even when they turn off the main road and go waltzing through an empty industrial estate?

I also think the writers did Rhys a really bad turn about the "no such thing as aliens" speech. Come on, what else did he think it was? A squid on growth hormones?

Maybe Owen has noticed Tosh, but isn't interested and is trying to let her down lightly by pretending he's not aware of her feelings?
