By any chance do you think he tells himself before the scene is shot that its MONA whom he is acting with... pretending to himself😉😉 all to get the scenes right.
Maybe MS is going to do a cameo and be the girl from the past.
I hope it is MS. At least we will see them together again for some good chemical reactions. But SS has more chances of getting this job because she is an EXPERIENCED BHOOT.😆
