Robert attends Lachlan's trial with Diane, Victoria and Bernice where they express their disgust at Chrissie for not admitting to framing Andy and letting her son take the fall for everything. Lachlan is acquitted of attempted murder but the judge reminds the teen that he had already pleaded guilty to perjury and is therefore remanded in custody, leaving the Whites in shock and the Sugdens delighted with the result. Following a suggestion from Charity, Robert and Aaron flip a coin and decide to have a secret wedding in Vegas. However, the next day, Robert is celebrating a business deal with Rebecca when Aaron bursts in. Fed up with his insecurity and jealousy, this leads to a heated argument between the pair, after which Robert tells Aaron he can't do this anymore and removes his engagement ring. Later that night, after a chat with Vic, Robert tells Aaron he doesn't want to give up on them but they are interrupted by the police who arrest Aaron for attacking Finn's love interest Kasim. Aaron is released on bail the next day and offers Robert the chance to walk away for good but Robert promises to stick by him.
