Next time on Home and Away, Robbo is pushed over the edge - take a look at this exclusive sneak peek of the next episode from Summer Bay here.
After Robbo completely loses it, a frantic Kat rings the sergeant and says she needs police units down at the pier.
She is later reprimanded for her handling of the case when her superior berates her, saying "Look at this Kat, all the evidence you kept from us."
Robbo later creeps up on Kat, ordering her to stay quiet, what is his plan?
Also on the show, Ben gives Ziggy and Brody his blessing.
Home and Away continues on RTÉ One at 1.30pm and on RTÉ2 at 6.30pm, Monday to Friday.
