Archers speculation

The BBC have decided in their 'wisdom' to warn people that the 2 January epsiode of The Archers will contain two shocks one of which will shock Ambridge to its core. Speculation is obviously rife, here are my ideas:
1) Will and Ed finally bury the hatchet, in each other
2) Helen and Ian finally get it on, Adam discovers them and runs amok in the village with the combine-harvester
3) Linda Snell gets a bad review in the Echo for the village panto and wreaks her revenge by getting Robert to disable the Borsetshire traffic lights causing multiple pile-ups

What ideas do you have?
