Alekh is known to be a notorious alcoholic...who drink alcohol like water
He never seems to get affected by it..He is never shown to get a hangover..Ya he sometimes does gets lousy but otherwise he is very active in his daily routine..
Then how come just before the mission he gets this terrible hangover which refuses to go even after 12 hours
I feel that the drink was sent by Ritu and she spiked it...Cause Alekh is one of the best and the strongest cadets...
