I wouldn't expect anything before episode 6. Maybe a kiss, but that's it. I'd love to be wrong though. A lot will depend on how long the episodes will be and how many of them are going to be in total. If they keep the current format of around 1500 renders per episode, then I think we are going to have to wait for while, because it wouldn't really make sense story-wise with how slow things are moving, at least when it comes to MC and Mia. Unless they get drunk or high or something and just go for it in the next episode, but I think that's unlikely.
