I don't know. As I understand it the Eliminator did not use the generator on May 6/7, but instead used power at the hangar. Given that, what we have left is a text about a guy going somewhere he goes virtually every day (Waterloo), mentioning a BBQ related task for that week, on a week where there was an actual barbecue at Maplegate but no scheduled test drives, in the middle of a series of texts that don't appear to be about anything identifiably ominous, proximate to a text about a generator that was not used in the crime. Hopefully even those that find the texts damning can see that those of us who can't use these towards guilt are not being frivolous.
What I wonder is was there an actual barbecue at the farm? I mean what barbecue business could he have at the farm? Did he have a freezer full of meat there? Propane tanks? If he did, don't you think his defence team might have mentioned that on that night Millard picked up a barbecue that was stored at the farm and brought it to Maplegate? No, because it just never happened.
