Meanwhile, Paul Robinson is furious when he discovers that Sienna could be responsible for his niece's death and angrily confronts Brennan at Kate's grave.
After hearing the news from Matt, Paul (Stefan Dennis) turns up at the graveyard and is furious to discover that Brennan is already there.
As Brennan tries to explain that he isn't even convinced that Sienna was responsible, Paul isn't willing to listen and rants at Brennan.
Paul tells Brennan that every lead in Kate's death so far has linked back to Brennan and the fact that Sienna is now being questioned is proof of that.
Devastated by the latest turn of events, Brennan walks off despondently, but is Sienna really responsible for Kate's death?
Paul and Brennan confront each other at Kate's grave.
