I think the R/willing scene is going to happen in ep 11/12 (so the week after next). Jee does consent to it and aggravates him (she's actually the one insisting they sleep together because at first he said he wouldn't). Even though she doesn't want to, she physically accepts it as she thinks this will be the last thing she does for him. His excuse is that this is his revenge for Dil. Tbh, that's kinda messed up because I don't think any gf would want their bf to sleep with another woman so soon after their death for "revenge", but anyway... they part ways and are both heartbroken.
I think (not 100% sure though) that the scene where he goes to the shoot and pulls her across his lap in the car is the next day (so it will be shown in the same episode or the next one), and then there is the scene where they are found kissing by Chayan and Suki on the couch. The latest teaser shows those scenes for those who haven't seen it.
