What does Agrippa REALLY say?

[Serena]

I listened to him, because sometimes having a friendly voice around was nicer then dodging monsters or finding out about disturbing torture practices

Yes! Having someone to listen to was great. Finally, I met a friendly living (well, kind of) soul in that forsaken castle!

Totally agree; Agrippas was the first human voice I'd heard that wasnt screaming horrible death. I was both off-put and relieved when I first met him. It was a great place to take a break and let the shock of everything soak in for a bit, very well done hub-level. I sat down specifically hoping Agrippa had some information that could help me understand what was going on, and indeed he did.
He explains why Alexander has his spirit trapped and even hints at some kind of battle between the two of them, or perhaps some treachery. I went from frantically happy to see him to suddenly wary cuz I realized there simply were no good-guys in the world, regardless of the conviction or sense of noble-ness any of them thought they had. I was a pawn in a battle for other-worldly power; whether Agrippa or Alexander's motivations for wanting that power were ethical or not.

Long story short, Agrippa really says 'lets GTFO out of here'. Whether Agrippa's Ending or Alexander's Ending were more nobler or just than the other is unknown to me.
