Lucy Beale was recently killed in the BBC One soap and Ben, who plays Lucy's twin brother Peter Beale, admits he was disappointed his "good friend" Hetti Bywater was axed from the show.
He told Attitude magazine: "I get on well with Hetti. I'm really sad that she's leaving, we were really good friends. So that's a shame."
But, despite that, Ben is very excited about the Lucy Beale murder plot - and, while he has no idea who killed Lucy, the actor is definitely enjoying filming the difficult emotional scenes.
He explained: "The first few months I was on the show I was doing some good stuff - love story, little secret."
"But to get such a big storyline with me and Adam... the reactions to the death of Lucy were really challenging but also something I was really looking forward to getting stuck into."
Does Ben think Peter could have killed his twin sister?
"I'd be excited to play it but I don't think Peter has got enough motive.
”I don't think it would fit the character."
Fans have plenty of time to try and work out who’s guilty, as the murderer’s identity won’t actually be revealed until February 2015.
