I think every thing seemed somewhat logical except for 1 thing :
Archna's dialogue about I also know the truth , CV 's deliberate drag on this --- when she could have easily said I also found out today about this. And all her prior action would have supported the fact .
The issue of Manav and Archana is toal drag ---- and if they did want to show the distance agin they could have chosen that Manav was angry because OVi was getting hurt and the reason was Archna's adopted daughter .
As of Arujun loving Ovi : I do not watch PV regularly but if I remember correctly, while back back when everyone was in Canada , Arjun had not agreed to love/ marry Ovi they were very good Child hood friends, OVi and family basically forced Arjun in to this engagement ---- thois thing should be pointed out to Arjun before he throws off the friendship with DK.
