Nick's sarcasm, pessimism, and self-centered cynicism arguably make him the most antagonistic character in the series. Almost everyone he meets quickly picks up on these attributes and takes a wary or active dislike to him. Nick's autonomous personality makes him reluctant to integrate fully with the group. In "Dead Center", he either tells the others not to bother remembering his name as he does not intend to stay with them long, or forgoes mentioning his name when asked.
