Actually a filler, but the entry has a long term impact.
They are creating a fertile field for extention of the serial. Look at the loose ends the story tellers have left. Vinu being adapted, Saahas (Virat Chavan), Harini..and of course Savi the bulldozer.
If the TRP rules, then they may show another leap. Terminate some more characters (BK, Ash, Ninad, Omi, Sonali) and carry the story with these new ones. Just my hunch.
Actually sahas n Savi ka love story Ho sakta hai after a big leap .. or they can show Vinayak was really not Sairat son .. and he goes away with patralekha.. ( real michhil was taken away from Rono and he had intended pekhom to marry michhil .. so michhil becomes his son .. emon knew that .. even Shruti wanted that )
But Vinayak n Savi are shown as brother , sisters so sahas is a better candidate
