Apparently it's being written into EE. No doubt there will be a long drawn out yarn about whether it's Alfie's or Andy's. Now that's certainly one way of repaying the £10 grand!
Imagine the conversation. "Now little Alfie, your real dad is Andy, who I was going to marry but dumped at the alter for Alfie senior, who borrowed £10k from Andy to pay off the rapist of Auntie Mo, that Grandad beat to a pulp and went to jail for. I shagged Andy to repay the money after he had Alfie Senior beaten to a pulp. And you are the happy result of all that. Simple really. Night night sweetheart."
