You have to change the sentence/topic from one contestant to other but you need to keep current contestants name in your sentence/topic ...Here is example
current post is saying
Amey sung Laga chunari ma daag awesome
Now suppor Minal fan want to change topic to minal he /she will say
Minal find Amey Hot ..( now topic is changed to minal but while changing they have to talk about previous topic contestant )
Once topic is changed to Minal then Minal fan can talk about her only ...
Now suppose Antara fan wanna change topic to Anatara he/she can do it but he/she have to keep Minal's name while changing topic
Like
Minal and antara are the only two gals left in Idol
If Karunya fan wanna change from antra to karu then he /she have to take antara's name
like - Antara and karu should sing one duet 😛
