I don't think a pregnancy for Minnie might be on the cards. Especially with Mickey. While impulsive, Minnie does seem to have some sense of how this world works and exactly how cruel it can be. Seeing her mother and now Meeta's ordeal she'll have to be really dense to get involved in such a situation.
Not to mention her aversion to anything related to love. It was actually a cute episode today in the sense that she didn't turn her nose up at the mention of love (if only to tease all the ladies around her). She was still focused on her growth rather than love during her own palm reading. I would've liked to hear her response to a new love arriving in Babita's life. But oh well.
Mickey too has been shown to have a swear from his mom to not touch a girl before marriage and he upholds it.
If they show Minnie pregnant (especially with Mickey in the mix) it'll look absolutely nonsensical with how their characters have been shaped up till date. I don't know how the writers with justify bringing that angle in and for what exactly.
If anything, I feel she'll rebel for her passion and work. (I don't think she should have to with HS counselling Babita though.)
My two cents. No offence intended.
