Do you think Karan will manage to get the whole family to go Haridwar?
yes
Or will Meera and Mohini manage to stop the trip all together?
no
If they do reach Haridwar will Tulsi reunite with the family i.e. Karan, Ba, Mihir, Tanya, Damini, Sahil, Nakul, Lakshya etc?
not right now..but i do think the Krishna and Tulsi Krishna will meet
