>>47486624He was starting to lose himself in his jealousy and anger towards (You) the player. He believed he was this know it all smart ass until you humbled him over and over again. He thought he knew better than Alder even, constantly questioning Alder's decisions and disrespecting him at every turn. It wasn't until Marshal buck broke him and told him to stfu that he snapped out of it. If it weren't for Alder/Marshal he would've become consumed by his envy.
This was all very subtle and you were constantly shown/given hints of Cheren's superiority complex. He was the complete opposite of Bianca who arguably had greater character growth than Cheren but it is more in your face when compared to Cheren. However Cheren grew a lot from the beginning of BW to the Beginning of BW2.
It's very obvious none of you played BW so *yawn*.
