Why rachana didnt mention about rags rape?

I watched ASHNA interview, where only ashish and rachana spoke. Rachana said..kalpi baked a cake...she is happy to celebrate his birthday and he is also happy.. Kalpi is worried khi may crate some problem. This is nothing to do with what we saw yesterday. I mean...they are celebrating his birthday..means...nothing happened last night. And rags is not raped?
