It must be??

Why else would Grace not grass up Mercedes for shooting her? Then why else get her to get rid if that gun? That must mean Grace killed Fraser and she knows if she grasses Mercedes up she will be in prison too!

But then there's the question of who's gun was the one Ste had that JP got rid of?

Very interesting stuff...

Doesn't the gun tie her to Joe...? But I suppose that could mean Fraser too.

Just thought the gun Fraser had with him that he gave Grace that night wasn't actually used to shoot him, maybe it's a red herring, Ste and JP and also us viewers think that's the gun that killed Fraser when it was actually the gun Grace has that she also shot Joe with.

Also there was Ray? the drug dealer that Grace killed.Could tie her to that murder.

Oh yeah! I think that's why she's so desperate to get rid of that gun, because she was found Not Guilty for Joe's attempted murder and could easily still blame it all on Fraser still but then there's Ray and Faser's murder that I think the gun ties her to.

Since when was Mercedes Browning a cold blooded serial killer. What the hell!
I cannot even understand why she shot Grace, , that's taking it too far, surely

Shot Grace by accident didn't she? Yes, she threatened to shoot her but doubtful she was ever going to! Just wanted the money!!

Did you watch it? It was an accident, she didn't shoot her in cold blood

Did you not watch the show??

She smother by accident. Also she's NOT a serial killer, a serial killer is officially a serial killer when they have killed 3 people. Mercedes has only killed once - Dr Browning and even then it wasn't in cold blood it was more self defence.

Does anyone know when we will find out who killed Fraser anyway?

I was thinking that gun could be the one that killed Fraser.

It does make sence and the other gun was used to throw us off.
