Title
The title refers mainly to the Team, who goes undercover as circus performers in Haly's Circus. Also, Robin's performance as a team member is jeopardized for a moment when he is seemingly assailed by a malady. Additionally, it turns out that one member of the circus family is pretending to be someone else. Thus, he was performing for most of the episode. In the end of the episode, Robin acquiesces to Haly's request and does one last performance for old times' sake.
