Mansi, nice analysis. The CVs are not only showing how Ruqu is manipulating Salim with Opium but are also showing how she supports him always invariably whether he was right or wrong. While on the other hand both Jalal & Jodha are trying to impose discipline in him as he is going to be the future Bhadshah thinking he should be fair in what ever he does and should learn every trade of warfare and administration. On the other hand Ruqu is pampering him saying, he will be the future king and each and everyone should bow to his wish and he needs to learn to command.
So as a child, he will prefer Ruqu's advise which are easy to follow than his own parents as to achieve that, he needs to work hard & sweat. If a any small kid, given a chance will choose sweets over medicine even though medicine will help him to grow better just because it tastes bitter.And CVs are also trying to bring in the factor how Salim Anarkali love story started despite they were at loggerheads to start with. By sending Salim to Kabhir's house, he will be in constant touch with Nadira and as the day goes, their friendship will start and will end up with Love / infatuation.
