It is very possible that Urvashi paid the goon to name kakisa. Urvashi must have told goon to threaten her and if caught he must name kakisa. She might have done this to tae revenge on kakisa for spreading pics of her and brijesh's wedding on the bed.
Urvashi does not spare any one. Also she wants kakisa to feel so bad that kakisa might do something drastic like commiting suicide or may be she will down grade kakisa so much then kill her and say she commited suicide
what say friends?
