Nial had no idea where the others were but they should be fine.

They were strong and independent. Thus, Nial followed Timothèe to meet up with his group. Timothée's first impression had changed quite a bit. If he had seemed aloof and arrogant before, he was much easier to approach now.

Nial was not sure why his behavior had changed so drastically, but he presumed that Timothée was concerned about the gazes of the people around them. Many Elves and rather powerful Originals were looking at him and Nial. This was rare for Timothée even though he was fairly talented.

That was also why he glanced to his side to look at Nial every now and then.
