Last night, viewers saw Ben tell Ian the truth about Heather's murder, fearing that Phil was about to turn him in to the police.
Ian (Adam Woodyatt) initially refuses to believe that Ben (Joshua Pascoe) was responsible for the crime, thinking that this is another one of the teenager's twisted lies. However, it soon dawns on the businessman that his half-brother is entirely serious.
Horrified by what he is hearing, Ian rushes out of his house and heads to the allotments for time to think - but Ben follows closely behind.
Ben begs Ian to believe that Heather's tragic demise was an accident, but has he made things worse for himself by sharing his guilty secret?
