When Patterson tracks down Kathy Gustafson (aka Electra), one of the Three Blind Mice hackers, she mentions that Kathy works for the 'Nerd Herd' - a technical support team working out of the fictional electronics store 'Buy More'. 'Buy More' was first introduced in a spy TV show Chuck (2007).
When Kathy is brought in for questioning, she is wearing her Nerd Herd uniform - a standard white shirt, gray tie and red pocket protector; the same uniform Chuck wore in almost every episode, presumably placing 'Blindspot' into the same universe as Chuck's version of the CIA.
The title of this episode breaks the pattern as it is not a palindrome.
