Instead she might just go back to RK and return the photos . Then RK might feel it is another Ahsaan done by MB \
on him and might be ready to say sorry to Paddy.
Another reason I can think of is, since Radhaji has heard everything and she was shocked when RK said "...jaise maine tumhari Maa ka apana kya ..." , so Radhaji might go to MB's home to ask forgiveness on behalf of RK. and it will come in news and RK will fume again. but then it woon't be actually RK saying sorry...but just thought this could be possible as RK saying sorry seems very diff. at this point.
What do you say ? any other guesses?
