It would be interesting if they went with that, but then you probably wouldn't get as much of an emotional attachment to the characters.
I'm not sure I would want to play as Clementine in the second season, it would envolve a huge time jump to make her 'playable' and I'm not sure that would help the series, just too much time would have passed and a lot would have to be explained. Plus, I fucking hate Omid and Krista so I don't want to control or see either of those two again
