Harry may have been the first to take up the name, but he was certainly not the last. When it occurred to the staff that they could take on the name Midnight, fervor and zeal spread through the masses. No longer would they only have one name. No longer would they have no origin. They would be one family.
But just as quickly as the excitement spread, so too did fear and hesitation. Unlike Harry, who was acknowledged by all, and had a special relationship with the Innkeeper, most others felt unworthy of the name.
On one hand they yearned for the name and all it entailed, but on the other hand because of the immense worship they felt for the name and its prestige, they felt unworthy to adopt it. They dare not admit to anyone the struggle they felt, yet they could not come up with an answer to their internal struggle.
