Tom comes back (as we all know he is due to recent actor change), blames Johnny for the accident and falls out with Helen for giving up her business for Rob and for leaving Henry on the day of the accident. Tony, in recovery, tries to keep the peace whilst Pat frets pathetically in the background, trying to reason between Tom and Tony falling out about the blame game/cow situation. Helen feels even more isolated from her family and relies even more heavily on Rob, further compounding his control over her and Henry (just in time for his sprog to Ex arriving). Johnny, as a result of the blame from Tom, goes off the rails and only stays because of his guilt about Tony and Pat's desperate attempts to keep him in Ambridge, leading to Johnny having suicidal thoughts and possible attempt on his own life, just like his poor deceased dad that he never knew. Cue much repentance from Tom (which will inevitably be short lived) and a potential eye opener for Helen, with Rob going all psycho stalker on her.
That should keep them going until the Christmas disaster storyline.
