Max spent time with Derek (Jamie Foreman) away from Albert Square late last year after on-off partner Tanya had rejected him. Despite hints that the siblings were getting up to no good, viewers have not yet discovered the full story of what went on.
However, Wood has now told Inside Soap that the truth will be revealed in the coming months.

"Jamie Foreman and I are in on it, and we've got a firm sense of what Max and Derek got up to."
The actor also expressed delight over the way Derek has shaken up life for the Branning family in recent months.
