@Sidra....Hmm...Dunno what to say exactly
Well my analysis of Harshad saying ''thanks'' to Aditi could be...
''Harsh is giving his speech where he is thanking all the technicians...So Aditi interrupts him in the middle and completes the list of the remaining technicians.....So maybe he was thanking her for completing the list''😛😆
Now dont kill me...This is just my view point😆
