What is Chaitu's Relation with Nag?

The long pending dream of Akkineni Fans to see all three generation actors from this reputed clan together on screen is going to be fulfilled with ‘Manam’ which is in final stages of scripting. As far information from inner sources are considered, ‘Manam’ will go on floors next month with ANR, Nagarjuna and Naga Chaitanya in main roles while Shriya, Samanta will partner with last two names. 

Meanwhile, Akkineni Fans are expressing doubts on how will Chaitu and Nag be related in the film? Will they represent two generations in the form of son and father roles or anything different? If this is the case then Shriya will have to do the Mother or at least a Mother like elderly character to Chaitu which also means Mother-In-Law to Samanta. This is quite interesting…isn’t it?
