The previously announced plot will see a fire rip through the village, leaving at least two villagers dead. However, residents will soon discover that the blaze was no accident and that one of their neighbours could be the arsonist responsible.
Speaking to Digital Spy, Lister recently teased that Carl would be "in the frame" following the tragic events.
In a separate interview with Holy Soap, he added: "Carl makes everyone aware of the fire and helps rescue people from the building - he's in the midst of all that but he also finds himself in the midst of where the blame lies."
He added: "I think it's going to be a great episode. It's going to kick us off with a bang [in 2011]."
