'Still inside?'
Once he left the testing room, Damian was slightly curious about what the other two had done. More precisely, he was curious about the identity of their Special Abilities.
However, since the rest of the doors were originally closed as well, Damian had no way of knowing if the other two finished their Assessment, and even if he did, he couldn't just ask them about their results without any prior interaction.
'Probably.'
That being said, Damian believed that he finished the whole thing pretty quickly. Unless the other two were stopped by the first or the second target, they should be still in the questioning phase.
On the other hand, if their Ability Class was different, they were likely to spend even more time inside. After all, when it was no longer just about hitting things, gauging an ability wasn't that simple, especially when it was a Support Ability.
