The one good thing to come out of dragon's "death" is that Colin should now be aware of just how backdoory Saint and Co are with Dragons tech/programming. Hoefully he can' use his tinkering to cut them off at the knees.Saint certainly believes it is, which handily plays into his self-justification narrative. Which, I mean, he's accepted a contract to open the Birdcage, so we're not talking the most reliable of narrators here.
I loved Dragon, easily one of my favourite AIs in fiction.
Yeah, Imma just going to join the line of people who want to punch Saint in the crotch. He's directly responsible for the suits not being online in time to stop Jack entering Nilbogtown, which by itself is pretty damn rotten, to say the least. And he's kidding himself if he believes he's a suitable replacement for all the plates Dragon was keeping spinning on all those poles - so much of the unnoticed, little things the PRT/Protectorate/Everyone has been counting on are all just going to slowly crash, one after the other, and it's not going to be pretty.
