If you read my posts you´ll see that i am VERY aware that much of the Sophia-Edwin meeting was a test for currently debatable reasons. Not only I, the player, but Edwin himself is also aware of that fact, you can see it in the ingame character pages.
Nevertheless our MC and Sophia connected via their shared nerdiness quite well (depending on our choices here). Sophia is an amoral genius nerd, cold, calculating and eccentric. As mentioned as cold as she is/can be, she could have easily sat out anything that happened in the blue room while watching the Carnations, neither Kath nor Edwin would have been surprised. Instead she chose to become involved and we can get quite a makeout sesssion with her.
During the "home invasion" we can also get some banter berween Edwin and Sophia and even the scene
ImSenjou showed in his post. No, Sophia and Edwin are not there yet, but they show some real chemistry and connection. What will come from that, we will see (and decide) in further updates.
