I'm sorry but this chrissie and sam thing is totally wacko.... Apparently sam is arrested for dens murder because chrissie frames her and Stacy Slater provides Zoe with an alibi. Then billy comes to sam's rescue!!!
This is ridiculous, come on, in real life all they would need to do is take fingerprints and any other dna from den's body to realise that all three of them handled his body.
Sam needs a little bit of light relief before she leaves for good.
