Yes because it's quite obvious now that ranbir is the kind of person who won't understand his feelings through words by others, but only via situations. It will take specific situations for him to realise how he really feels for prachi, especially when he is forced to question his reactions and behaviour towards or around prachi.
The problem is even after reacting in a certain way, in this case possessive, he never questions why he is behaving like that. It was only the push by Aryan that made him accept his protectiveness for Prachi. So, situation followed by a major push through words is what he needs.
