"Me?"
Jamie looked shocked as he pointed his finger at himself while looking at the judges.
"Yes, you. I want to swap with you," William replied with a smirk.
"Why?" Jamie asked, completely confused.
To be honest, Ari had the same question.
Why my team when there are 6 others for you to join!
Even then, there's nothing wrong with your team!
Stay over there!
Even if Mathew left, William's team was full of mostly talented people, including three people he had first performed with.
If he stayed there, he would easily get the best vocal parts for whatever song was chosen and would probably be the leader.
It made absolutely no sense moving to Ari's team, which contained a person with whom he had a conflict (Benjamin), and the team was vocally stacked, even when considering those who specialized in dancing and rap (apart from Matthew and Vishal).
