Please Help!

Hi everyone. I've been a silent reader on this forum, but I have fallen in love with Omkara and Gauri and had wanted to write a small SS on them! However, I actually missed quite a few episodes in between, with Kaali Thakur and Swetlana being exposed. Would someone be able to give me a super quick update on those episodes, or direct me to a page where I can get the info?
