No Armaan is not to be blamed. Armaan was sharing his doubt with Atul to reaasure him that he didnt suspect him when by chance Dr Keerti overheard the convo. It wasnt as if Armaan had planned all this. Besides Ridz as always told him "mujhe jaana hoga😡" & went away. Btw I am most irritated by this dialogue😡 😡.
If Atul can sense that Armaan is suspecting him then Ridz knows that Armaan saw the propanol vial in her hand then shdnt she on her own conscious/sixth sense clarify to Armaan?
