is the tick part of arthur's imagination
In the Amazon Prime video series, The Tick is fixated on Arthur, and even mentions at one point that his thinking is fuzzy when away from Arthur. Despite Arthur's repeated attempts to push The Tick away, the hero won't leave Arthur's side for long. The Tick also frequently talks about Destiny as if she is a literal person, guiding Arthur's path (``Destiny gave him the suit. I just acted in more of a 'delivery man' role''), alluding to the Parcae in Roman mythology. At one point, Arthur starts to believe that The Tick is merely another hallucination, but that thought is quickly dispelled when Arthur's sister, Dot, interacts with ``The Blue Guy.''
