I had wondered why he was so worried about Alex being found because there would be no evidence. I don't know if anyone knew he had seen Alex or was there not a situation with Edna or Alex's gran where Cameron said he had seen Alex or heard from him explaining why he had just disappeared? I'm confuzzled too :/
Also confused about Sarah's wigs - surely her hair would have grown back by now in the storyline? Why a short one earlier this week, now back to a long one again tonight. Why does she often still wear a scarf? Do you think she lost her hair in real life too?
