If TMKOC creatives go a little adventurous, they could make this scooter track more interesting instead of stretching it like a rubber band for so many days.
Once the elders (Bhide, Jetha, hathi, Sodhi etc) have finished dealing with the issue, they could show Sonu getting upset with Tapu and others about stealing the scooter. I have always wondered how Sonu is so cool about Tapu sena cracking jokes on Bhide. She never gets upset like how Tapu gets mad if anyone talks bad about Jetha.
If now she comes to know that Tapu did this without involving her and also took her father's scooter without permission, she can be shown to be angry at them. Some conflict within Tapu sena and how they deal with this and come out as better friends would be a nice change to see instead of all this goody goody friendship. It is also natural at this age to have small fights within friends.
But of coarse this is possible only if they are shown to be acting their age instead of this over mature behaviour !
