Why wait until now?
He's been onboard with this plan since The Queen. Now he has doubts? Not buying it.
That as IMO the point of his conversation with Keller and I think he always had some doubts about the plan that's why he altered if somewhat in The Queen nad Teyla wasn't going to allow him to get away from the plan she made that pretty clear at the end of The Queen.
What exactly is Teyla gonna do to stop Todd? If I was him, I wouldn't be losing sleep about her 'threat'. She can't play the 'Queen' card again, it would be easy for Todd to expose her ("My highness, I've brought you a human to feed upon....what do you mean your not hungry?")
Even if Teyla (somehow) forced Todd to honour the deal, other Wraith won't be as accommodating. Why have Apples when you can have Farmers?![]()
Well Maybe Todd is thinking with the dwindling food supply maybe just the foot soldiers would have the "software patch" and the higher ups could feast on the humans so that one planet could supply all the needs of the ruling elite wraith while the foot soldiers can go raid farms instead of killing the farmers.
If the Wraith showed up and instead of culling they stole my apples, I would be a grateful Pegasus resident. and may even offer a few bad people for the elites to feast upon!
