Also both Dr.Archala and Suraj Singh arrived in the drama around the same time.
Also both are kinda similar....... Dr.Archala removed Raunak from the mental asylum and back into K.Mansion. However it turned out that she was using the same medication that the doctor at the mental asylum was using..... the ones she was criticising.
Suraj Singh used the same marketing strategy that Mantra suggested. he criticised the strategy saying its too old, when like Dr.Archala he used what he said was wrong.
Plus whenever Dr.Archala's nurse, disappears, I reckon she's telling either Suraj Singh or Dr.Archala any information that she finds.... or why would Dr.Archala be trying to get that nurse to come back, when Ishita asked for the nurse to be changed, as she kept on disappearing.
Don't know about you guys but I think that Dr.Archala is related to Suraj Singh, probably his wife.
