Do you love her?

me with the idea of Olrox adopting Richter:

Like, the first scene has Julia apologizing for sending Richter to France, to which Olrox tries to tell him "there's always a choice".

It's established that Tera told Maria that she fled from Russia because she didn't have a choice, and when Tera tells the real reason, she admits that not having a choice was the simple version.

We don't get an explicit "I have/don't have a choice" for a while, but Annette goes into her time as a slave and her decision to run away and even join a revolt, marking a choice she made when she seemingly didn't have one.

A bit later in the series, Olrox gets "there's always a choice" thrown right back at him, though eventually, Richter kind of has to use the book that Olrox stole and gave to him and his friends.

Edouard tries to encourage the other night creatures to embrace the memories they had as living humans, and chooses to stay in the abbey when Annette offered him the chance to escape. Jacques even says that he liked what Maria said, and the last time we saw him, Maria said he was at the revolutionary meeting.

Green for a friendly starter

"Are you quite alright?" She asked, sitting down near him. She was going to pour him something warm to drink, but...

"You have that face you make when something is troubling you."

She doesn't even have blood.

That said, she does seem to understand your situation well enough. Or at least the part of your situation where you need to feed on blood. You've figured out that she's a monster of some sort, but you're not entirely sure you want to find out what exactly she is.

The least you could do is greet her.
