Martin is another story. I think it’s a mistake to make it into a bbc fascination, and call it a day. With Ryan, we scripted in the “let me protect my model from assholes” but to move the relationship along. How we will work in Martin, I’m not yet sure, but we’ll give it the old college try.
I think a fairly simple and realistic buildup would be when he comes to get his van, D/F and him go to a restaurant or something and Martin lets D drive the van (didn't she already do that?).
- Go to a restaurant (to chat, catch up with each other etc.)
- *Choice* D drives the van
- *Choice* Perhaps Martin sits in the backseat behind D and puts his hand on her shoulder to encourage her.
- *Choice* D and or Martin flirt (about the driving skills of D for example)
- Martin spends the night, which would lead to the sharing if the player didn't reject the previous choices.
Maybe they even run into Olivia/Graham there and have a quick chat, if you want the sharing paths to overlap some.
