Emma crossed her arms as she leaned on a bed near Simon, not sitting down. She was enjoying listening but he must have noticed her momentary confusion about the leeches comment considering he went on to explain it straight after. "Interesting, you do seem to know a lot of random things but I guess that's what comes with you sticking your nose in a book all day" While she wasn't such a fan of reading herself, Simon often told her allsorts of weird and wonderful knowledge he'd discovered and she did remember anything that took her interest. It wasn't clear how much of it was the facts themselves or how Simon told her them, but she did try to remember it. At Simon's indication to sit down, she pretty much flung herself onto the bed in a not very professional manner. She did know that they were expecting to be joined soon though so she did adjust into a more respectable looking position that wouldn't look bad if anyone walked in. However at Simon's sobering comment about slavery, her demeanour became more serious anyway and she looked at Simon directly. "This might be really bad, but slavery being a thing here doesn't surprise me at all. We already knew how elitist some of the races can be, they have a superiority complex that makes them think that they are better than everyone else. Even with the ones that don't, it's not uncommon for certain races to be looked down on. I mean we've come across quite a few that look down on us. With that attitude and a strength that surpasses those that they think inferior to themselves, it's not really that much a jump for them to capture them and treat them as slaves. Plus when you take into account all the fighting that goes on in the universe, I suspect it may be common practice to enslave any captured enemies instead of simply killing all of them." Emma sighed and looked down. "It's a harsh reality, it's not all happy endings. It's a big universe and while there is probably quite a lot of amazing people in it, there are bound to also be a lot of not very nice people. The more people and races there are, I guess the more likely it is that some are likely to be involved in slavery. Hell, even humans enslaved other humans in the past, are we any better? Also some of it won't even be a good and evil thing, it will just be a cultural thing for some species and they won't even realise how bad it is." She paused. "I'm sorry, I didn't mean to be all depressing." She smiled while looking up at him in the hope to lighten the mood a bit after saying what she said, though it wasn't as quite as natural as her usual smiles.
