A Tiger's last stand
When Vorden had asked this question, he thought back to the time when they had all been in the Shelter. Back then, he had seen Quinn, but not once had his friend used his shadow abilities. Even if he had obtained it at some point, that didn't explain the strange way the 'Quinn' before them spoke to them.
Vorden had gathered that most likely the person that was in control of Quinn before at the Shelter, would be the same person now, but he was interested to find out just who this person was, and was hoping to get an answer. The only problem was, Vorden didn't account for the fact that he had two hot headed brothers who were ready for action.
Immediately after Vorden voiced his doubt about the person in front of them being the actual Cursed faction leader, they considered him to be an enemy.
