I guess, he'll keep it to himself for now! But it would be interesting to see, how he behaves with his past lover who WAS and also IS destined to be his killer in this birth!
Also, I don't think ballu is only scared for that! Even right now, veer knows he's destined to be killed at the hands of aadi-naagin! Kuch aur bhi baat hai! I feel, there's a greater mystery surrounding veer!
See, Veer knows that Bani hates him so much that she can kill him also. But there is a difference between Aakesh and Veer, yaar. Logo ka punarjanam hota hai, because what they could not understand or realize in the past, they can fulfill now. And they are a refined version of their past selves. Veer is surely Aakesh when it comes to feelings, but bande ka dimaag teevra gati se daudta hai. So, if he remembers he is Aakesh, he will be overwhelmed by his feelings, but at the same time, Veer will use his dimaag to not repeat what happened before. And if people are scared that he will remember things, means bahut gorak dhanda kiya hoga Satyug me.
Ballu ka bhi koi gorak dhanda hoga, jiska pata Aakesh ko tha. But if that was the case, when Shakura came claiming he remembers it all, he was pretty chill yaar. Infact, he looked happy.
