Okay so i was looking at some things and i think your 400 days choices affect episode 4. Do you want to know why? Because i played 400 days two times to see if it affected anything in episode 1 (obviously not ) but when i was scrolling through the episode 4 photo on my first playthrough it was the regular photo, you know clem with all those people around her. Later i dont know if this is a glitch or something on my second playthrough everyone didnt go with tavia. So the episode 4 photo was different..... i looked it up online but i couldnt find it. I searched it on youtube and i found this video. Tell me what you guys think about this. Honestly im shocked and excited. (also if you think is stole this theory from the video i didnt. I have been predicting this for a week now i just have been using trial and error tactics.)
