yes, Astrid is dangerous, as the whole House Luzatto is. But nonetheless, she seems at least to value her friendship with Nyla.
Yes she would do a lot of shit, but in the end, the clown is just as Maskerade... a role she plays to hide her true feelings and her true personality. I ound it quite interesting that Simone told us not to get close to Astrid... and i asked myself why... Simone does not know us enough to truly care about us, but she might care about Astrid... so i guess she tries to protect Astrid, not us, in telling us not to come too close... which means, we seem to have the potential to pierce her veil sooner or later and see the true Astrid... and Simone tries to prevent that.
The fellow clown, distracting the Audience if the first clown struggles...
Characters like AStrid tend to play so many Roles that they seemingly forget who they really are, how they really feel... and i guess exactly that is her weakness... imagine if she would find out that she is in love with the MC, but would have to kill us for her goals in Sanctus... talk about broken hearts and souls...
But if she would decide to help the MC in overthrowing the king and getting control of the hearth...she would be hell of an ally.
perhaps she has a little, frithened girl inside, that plays all this roles to hide herself... and then some "hero" came and swept her off her feet, gives her a feeling of safety, no need fo the roles any more...
just some ideas...
