All 3 are possible in my opinion. Honestly, rather than Ashu's past mystery revealation, I am more interested in watching situation-1 which proves Nidhi's mettle as a brilliant Dr. & responsible, composed person to DD. situation-2 will be a mutual implication of 1 (This situation:2 was very very nicely shown in another show - SGP during the leads' HM in Goa) according to me.
SGP ka full form kya hae?
