I'm Ready
The first thing that came to Lucia's mind was that this had to be a joke. It was so surreal. It wasn't that she had a close connection to Robin Graylash, she didn't even know him, but it was something that their family had been wondering about for years.
It was never quite clear how he had managed to die or what had happened to him; they just knew the downfall of the Graylash family, her part of the Graylash family started then. Since she had heard of this from her family so much, the family's obsession had somewhat become her obsession.
To finally find out the answer, by some accident, it didn't feel real, which is why she chose to think of it as a joke, but looking at Quinn's face, it didn't seem to be. On top of that, Lucia started to think, when has she ever seen the person in front of her lie.
Apart from the lies that were made to cover up his identity, Quinn just wasn't that type of person, at least not to lie or joke like this when it was a serious moment.
