I have to go to work soon, so I'll leave those questions open. However, if I take the angle that you made a genuine slip for N2 and didn't think I would be able to return (or not as easily/quickly), then it leads straight into you giving Sunflower the bus to give yourself an alibi, as the others had at the time not called out the N2 contradiction as much, and I wouldn't be able to verify it--thereby allowing you to postulate that "scum" caused it.
