Yup even I think in rushing this track to wrap up they missed this
Or may be they have kept it this way knowingly so they can give this tack as open- end to Have Ishu more touchered and taunts from Simi and her mom and how raman defends her or even if he does not raman-Ishu coming close
ya they little bit rush d track by not focusing ishita after d fiasco n continuity n param half baked expose to left open room for simmi n toshi to ve their sense of humor with ishita n param hinted in epi by saying to simmi n raman tat he will be back n now on a break lol.
