1)However he might become mental i dont think he ever went mental i think he is perfectly fine and is now working in a hospital.The only reason he dint return was because he thought riddhima would hate him or he thought riddhima would have moved on in life.
2)Apart from this im not sure if what shashank ever told armaan was true and If armaan actually saw the reports properly. Shanky always wanted armaan to get out of riddhimas life and this was an easy way out for him by telling armaan that the chances of him going mental are 90% which could be a lie also.Im not a doctor though
3)Anyways whatever it is even if armaan is mental and if we see KSG return i think it would be a perfect role for karan to play and it would help him develop as an actor.then always riddhima will be the reason he would become normal again
I honestly dont think he is mental but i wonder what u guys think
