Emily's cleavage is BACK. I guarantee you that both the debut of her boobs this season -- as well as her affair with Adian -- are the results of a network note to sex this thing up. Which is actually not a note I disagree with. ANYWAY, Emily's undercover for Takeda on a gig to recover Colleen, Aiden's sister and lo and behold, who has also infiltrated the obviously extremely shady nightclub run by Russian Sex Traffickers to do the same? Aiden. This is before Aiden joined Tadeka's Ninja School For Thoughtful Self-Drowning, and how he and Emily met, which will be a wonderful story for their grandchildren.
