"!!!" Vina definitely missed this one. That was right. From the beginning, Clovis had only brought twenty people even though they had two representatives.
In the beginning, she only thought that this was Clovis' way to balance the strength of both parties. If the Three Swords brought thirty people to fill up that number, Clovis wouldn't be able to fight back if Eid chose to attack them.
If the Three Swords brought twenty people, it showed that Eid didn't respect and believe Clovis.
Hence, Eid agreed when Nathan proposed to bring ten people from each side.
Because of Reolf, Clovis suggested that they bring the fighters since Melody would become their operator and Rin came as a chef.
However, the moment the mission reached this point, the twenty-member limit was questioned again.
Clovis already knew that there was a traitor. If they assumed this was the main reason for the number of members instead of other reasons, other possibilities started to emerge.
