This is very much possible considering the fact that Agastya was himself a neglected child where he was thrown out of the house by Alka and then Daadi and Dhanraj warmed up to him. If indeed Agastya had a memory loss then his mind was a clean slate. So his mind automatically thought things which he was fed with.Originally posted by: Sunaina7
Or maybe This particular childhood memory was fed by malti into Agasthya brain when he had no memory after gaining consciousness.
But let us not waste our brains here. Hamara sab theories paani mein hi jaata hain.
