I dont know why but i have a feeling arshad will unite aditya and zoya..
In previous episode, he sensed that zoya is definitely much more than a friend to aditya but i think he also guessed aditya is also more than a friend to her. Now there is high possibility he might get to know aditya did a prank call..
Now there can be two situations arise from this:
1. Arshad will confront aditya and ask him why did he make a prank call and maybe aditya burst out his feelings to him and maybe arshad will help him to make zoya realise her feelimgs for aditya.
2. Arshad may tell about prank call to zoya in a way which make zoya angry on him and maybe she can distance herself from him.
My intuition is for 1st situation but the thing i learnt from this show that it is highly unpredictable...so maybe something different will happen
