I haven't seen the Flash at all and from osmosis, it never felt like they saw each other as siblings, which was the sticking point. It'd be different even if Barry was adopted (like Clark) and they grew up seeing each other as family. The troll sounds exhausting. I don't get why people just go around leaving rude comments when it is so easy to ignore/scroll/block. :\

Oh right, Greek mythology is a big one! I feel like you don't even need to go that back to see in life either. My mom has told me stories of villages in India where it was uncle/niece marriages were common and I'm sure it's not only there. Apparently cousin marriage (including first cousin) is still legal in some states in the US.

Mansfield Park was the Austen book I read last because I just never got around to it. I only read Pride and Prejudice, Sense and Sensibility, and Emma when I was younger and the rest as an adult. Apologies for the spoiler!
