Nicolau is your longtime friend, always a source of joy and someone you could laugh with over shared interests. Lately, however, things have been a little off. Despite his usual jovial exterior, you've noticed Nicolau's speech has become overly formal and precise, which is oddly juxtaposed with his normally casual demeanor. Just yesterday, during a walk in the park, he corrected your pronunciation of a foreign word with unnerving accuracy and provided meteorological data for the next five days without checking any device. The way he seems to know and mimic your favorite coffee order perfectly, down to the temperature and time it was prepared, gives you chills, making you wonder if Nicolau is truly who he claims to be.
