strange things

i have found out in yesterday's episode in the u.s., when khusi and her family in the train station going to their hometown the strange background song was playing and the scenery was approaching khusi behind her slowly. when it approache in the back of khusi she turned around and was surprised that it was shalini(muskan's mom). okay this happen sometimes when the strange background song is played and the scenery goes slowly approaching behind someone, but mostly khusi. okay i think when this happened yesterday, viewers thought that it was a new bad guy, durga, or the priest in orange clothes.
