It won't surprise me one bit if MS takes the stand to clear the fog left hanging in the courtroom by CN's testimony (and others). I have no doubt DM confided in MS and filled him in on what was discussed between him and CN, what she knew, her role and the lies she told on the stand to cover her own a$$ (DM's and MB also). In my post from the wee hours of this morning, I responded to MsSherlock's post suggesting it was MS who was with DM May 9th, to help him do whatever at the farmland and then load TB's truck into the trailer. These two were in cohoots and had a big secret to share so why wouldn't DM have informed MS that he confided in CN and was going to pick her up to help him with his "tiny mission" that night after DM dropped MS back off in Oakville, minutes prior to picking up CN. MS will be able to shed light on what CN knew about the truck theft and TB's murder. There were likely times she was present when DM and MS discussed their plans and after the fact. IMO I think MS could blow this case wide open and fill in so many blanks.
At this point MS has absolutely nothing to lose. I'm sure he is looking forward to having his version (the truth) of everything that happened during his stint of being DM goon and yes man heard. There can be no further damage to MS's character and his criminal past, drug and alcohol use, the fact he was a wannabe gangsta, working under the table for DM, helping DM carry out thefts, etc. It's all out in the open now so he has nothing to lose at this point. But that's JMO.
