Eye-witness found

in one episode when aayi (this lady is a crap...feels like smashing her head) asked for proof against krushna in support of the allegation...obviously pallavi was silent coz she herself knew bout it now but I was shocked to see Govind in such as well...I mean he knew it from the beginning and is the eyewitness of the incident, the proof which can take krishna behind the bars...why was he mum n ran away from the place without replying to aayi??
