Dickson doesn't seem to have a perfect route, but Leon does. For Leon I remember I had to always choose the option that refers to the dog and if you get to the point where you invite him to your place and you don't get a scene with Leon in the shower then you did something wrong. If I have time I'll look through some of the options again. It was easier for me to go through Chad's because of the rough draft others did. One interesting thing is I think Jacob might have a one off scene like Arthur had in The One or that gangster in My Soldier, because he has affection points, but I've spent way too much time trying to figure it out and can't get it. You can start it by making sure you get hit in the face by the football on Chad's route and then go to the football field on day 4 and choose, No it's not me, Sounds interesting, I know. That will boost his affection to 20, but I don't know what to do from there.
