Being blind he solved the case with same attitude as before or after...i cant think him as normal human...
For me they are above all normal things...i really cant explain why i reach to this conclusion...there is lots of incidents dialogs etc
One point may be i saw this case first time in 2009 when i have already a picture of trio in my mind...it can be a reason for which i cant consider ACP sir a normal human being at that point also...
