It's odd; when they first met it was Ian who was the 'wild' one of the two - always suggesting new possibilities (like having a baby with his friend) and urging Adam on. And Adam was very clear that he liked to think things through very slowly.
But somehow Ian has morphed into Mr Dull.
While across all that time it's been Adam breaking rules, sleeping in wayward caravans, insisting on his own way and never, never letting anything or anyone come between him and Home Farm soil. He is totally Brian.
I'd been wondering about the pre-eclampsia output. Unfortunately the SWs didn't know about Rob when they gave Helen the 60th anniversary birth emergency, so I guess they hadn't drawn up a SL specifically involving him - but they may still have planned to re-use the pre-eclampsia for any future pregnancy she had.
I wonder if there will never be any long term planning (Johnny's return, Phoebe coming into her familial inheritance) ever again.
