... plot questions NOT involving the origins of Nero. 
(spoilers)
I just finished my first play through, after wanting to play the game for years and just never getting around to it. I spent so much of the game thinking "Who the HELL is Nero?!?!" and not trying to piece together much else. Well, turns out no one really knows for sure who Nero is, BUT...
1. Why was Trish masquerading as Gloria? I assume to gather information on the Order, which I guess is why they busted in at the beginning of the game to try to kill Sanctus. But then, why did Lady have to then inform Dante and Trish about who the town's folk were and what they worshipped?
2. Wait... What... how did they get Sparda's sword, now?
3. Lastly, during the bonus ending, after protecting Kyrie, Lady and Trish blame Dante for "bringing Sparda into the spotlight." ... why? I thought they just always worshipped him.
Okay, possibly stupid questions, but they're bothering me none-the-less. Like I said, I spent so much of this game going "WHO ARE YOU NERO. I WANT TO PLAY DANTE."
