The overpass that Kate is driving on while pursuing Hush is the same one as in the opening scene of Deadpool (2016).
The page that can be read in Lucius Fox's journal, makes a significant reference to another hero entirely -Azrael or Jean-Paul Valley, is an agent of the Order of St Dumas, brainwashed to be their champion. Azrael took over as Batman when Batman's back was broken by Bane. However, Azrael's mental instability caused him to grow into a more extreme, violent, and reckless version of Batman, for whom Bruce Wayne had to return to take down. Azrael has since recovered and grown to be an important ally to the Batfamily. Most recently, a member of a team led by Batwoman herself. Lucius Fox's journal makes reference to Geoffrey De Cantonna, the Suit of Sorrows and the Order of St Dumas, all very important parts of Azrael's story. The Suit of Sorrows is, in fact, the very suit of armor that Jean-Paul Valley dons when taking on his Azrael persona. The journal shows that Batman retrieved the suit from Talia al Ghul after the resurrection of Ra's al Ghul (a reference to another classic DC storyline). Though he initially discounted rumors of the suit causing insanity, he found that wearing the suit was slowly driving him insane. What this has to do with the current Batsuit is uncertain, though the very next heading in the journal is titled 'The Means of Penetrating the Batsuit', implying that the Suit of Sorrows was somehow instrumental in the construction of the current Batsuit.
When Alice uses the glasses, the camera cut to show an excerpt from the journal. The relevant passage reads: "During the resurrection of Ra's al Ghul, Batman... suit of armor from Talia al Ghul, The Suit of Sorrows. According to its legends, it can impart strength and speed of its wearer but also would completely corrupt anyone whose heart and soul is not pure. At first, the Dark Knight was dubious of the legend, but eventually experienced an aggressive behavior while wearing the armor during patrols. Batman later learns from a member of The Order Of The Pure, a splinter faction of The Order Of St. Dumas, that the armor once belonged to a knight named Sir Geoffrey de Cantonna, who massacred hundreds of people in an alpine valley in 1190. The Suit of Sorrows becomes one of the trophy displays within the Batcave, to remind the Dark Knight that he must be ever vigilant not only in his crusade against crime, but also himself. The new Azrael takes up wearing the suit eventually."
One of the inmates freed when Alice opens all the cells is shorter with bushy hair, and gives a Psychotic Smirk to the camera for a bit. Presumably, this is meant to be Dr. Psycho.
