best cast is best

I wanted to do a romantic comedy with Jack and Ianto, and the obstacle between them getting together is a pterodactyl! But Gareth added a wonderful depth to it, when, unseen by Jack, he starts to cry at the end. Obviously, the unspoken thing is that Ianto wants to get in to Torchwood so he can keep his girlfriend Lisa alive, so that’s a beautiful bit of empathising by Gareth that wasn’t in the script. That’s the extraordinary thing about this cast: they never stop creating.
