[quote]Are dumb AIs like Auntie Dot affected by rampancy?[/quote] No. [quote]If Halsey has deserted humanity, then how does she give the eulogy to Noble Six in 2589?[/quote] There's no indication that she actually gave the speech in 2589, we just know that what's being visually depicted (the recolonisation of Reach) takes place then. Halsey could have said that at any point following the end of the whole arc surrounding Reach.
