In next week's string of episodes, viewers will see the pair's recent bickering come to a head in the midst of Todd’s involvement with con-man Adam Barlow (played by Sam Robertson), which led to the Underworld factory's catastrophic collapse.
First, Aidan Connor (Shayne Ward) tries to sabotage Todd and Billy's (Daniel Brocklebank) relationship when he gets wind of the businessman's shady involvement with his rival Adam.

Realising that Todd and Adam have swapped Colin Callen's signed contract with a forgery, Aidan storms into the solicitor's office to try and seize it back.
