Thoughts...
What if Matt's dad used to be a digidestined
What if Yolei and Ken got together
Will Kari will be possesed by the hangymons master, Marine devimon?
What if Something really tragic will happen to Davises sister just when everything seems ok?

I think Ken's brother is really important to the plot somehow, remember all the emphasis they put on Kari in digimon adventure?

Why didn't they put Kari in the fist series in the beginning?

Why wasn't Matts dad suspicious that Matt was running around with a digimon? Was he a digidestined?

Why didn't Izzy take apart his digivice, anyway?

Why did Kari and TK go on to 02, and not two others?

Why was Mimi so ditzy at the start of the first digimon?

Why is Davis the leader of the digidestined if they all left him behind when they went looking for the digimon emporers base?

Why do the Hangymon want Kari so much?

Why does Sora act so tough?

And why oh why does no - one think Tai and Mimi are made for each other?!!!

What if Izzy had taken apart his digivice?

What if Kari was not sick and she could come to camp?

What if Their teacher was a evil Digimon?

What if T.K. said he would not go with Puppetmon?

What if Matt's dad was a digidestined?

What if Gennai was a bad guy?

What if Tai picked the wrong card?

What if Ken's brother hadn't died?

What if The kids had never found Gatomon and Wizardmon hadn't saved her?
Why did Wizardmon become a ghost if all digimon get reborn, I mean... you have to die to become one...? and if it was because he was in the real world, does that mean that the digidestined would get reborn if they were killed in the digital world?
