When will vittal come to know?

I guess, kamla will come back, kalpi will get the sindoor some how, she will apply it. Vittal may come to know witth this convesation of kalpi and kamla. There is no other wAy he will come to knokw. Some how kamla after watching kalpi applying the sindoor sent by vittoba will shout at kalpi,say some thing in haste making vittal coming to know about it.
