trying to look for logic in a tv serial where the intention is to create drama. I am myself a doctor and my answer was only to those who said it is not possible to get high fever after eating the drama that followed after Dev fell sick I don't want to comment in that.
Anyway it seems clearly it was not new for Dev to have after eating ice cream,. regarding soft drinks you can thaw it before having it.Fair enough. I am not a doctor. So I will take your word for it. Then why Dev did not get this fever after their rain dance? He just had minor sneezes then. Also, if he has tonsillitis, then he can never eat any cold drinks ever, including scotch or whiskey on ice as he did on the night of Sona's date with Ritwik and engagement. How did he not get sick then?
