The number of beasts emerging from the shelter was much higher than they first thought.
However, the Originals could defeat them rather easily by using the surroundings to their advantage.
The beasts had to squeeze through the shelter's gate. Because of this, only a few beasts emerged outside the shelter at once.
Observing their attempts to escape was not actually necessary and Nial was rather bored.
This boredom lessened only a bit when answering Sam Anderson's questions. The Tritan-ranked Original was bombarding him with loads of questions and hoped to receive proper and detailed answers from Nial for each.
At the same time, Sam Anderson had a hard time accepting that Nial knew a lot more than he was supposed to.
Only when Nial chose to leave Sam Anderson's side, did the Windbreaker slowly comprehend that Nial's detailed answers were something not many should be able to know.
