Personally, I really enjoyed this episode - mainly because two of my favouritecharacters return to the series. That's what I really like about Casualty. When a fan favourite departs or gets killed off, they always introduce another good character (or in this case, they bring back two)!
I also found this episode quite tragic though. The little story line with Elliot and him trying to reunite with his biological mother is really sad and the moment he was hit by that van, oh god!
