Vanessa's final EastEnders episode aired last night, showing her team up with new lover Eddie Moon for revenge against his son Michael (Steve John Shepherd), under the impression that they could then head to Spain together.
However, in a final twist, Eddie dumped Vanessa at the last minute and she felt unable to return to Albert Square as she feared the police were investigating her theft at the boxing gym.
Lucker has now insisted that Eddie's decision was the right one due to the way Vanessa had plotted against him with Michael earlier this year.
She told BBC Three's EastEnders: The New Moons: "Eddie did the right thing in leaving Vanessa, because he can't trust her.
"As much as I would have loved to have seen Vanessa and Eddie run off into the sunset, I appreciate why Eddie did that."
David Essex's final scenes as Eddie also aired last night, but executive producer Bryan Kirkwood and scriptwriter Christopher Reason both expressed hope that he may return one day to continue his story with Michael.
Kirkwood said: "The man's a proper gent and he's a proper star, and I'm very hopeful that we haven't seen the back of Eddie or David in EastEnders."
Reason added: "Of course I'm sad to see Eddie Moon go, but I'm also hopeful that he'll come back. So stick around because the final showdown in [his] story has yet to be played."
