The story doesn't make sense. So the fictional friend drops them off for a test drive and heads to Tim Horton's. At this point it has been decided that DM and MS want to go on the test drive while fictional friend would rather have a coffee. But the plan would be for DM an MS to return to the field after the test drive. So who does the fact that fictional friend can't find Tim Horton's change things? Is he lonely? Scared? Why would he text DM and what would that change? Wouldn't fictional friend just go to the predetermined rendezvous point and wait for DM & MS to return?
Not that it matters because its a lie either way, just doesn't make sense is all.
I agree, which indicates to me if any of it is true, the dropping off of MS to pick up the Yukon was planned. And he knew the rest of the plan too.
