At 9:30 when Poe is displaying all the bounties one of them is director Uwe Boll.
Poe (Chris Connor) and Quellcrist Falconer (Renee Elise Goldsberry) are the only characters that are played by the same actors from season 1 on this episode that have reprised their roles for season 2.
Before the old AI hotel is repurposed, 'REI' is written in one of the windows. Probably a nod to the first season and that Harlan's World was their original home.
Anthony Mackie, Simone Missick, and Dina Sihanouk have all played characters in the Marvel Universe. Anthony Mackie plays Falcon in the Captain America and Avengers movies. Simone Missick plays Misty Knight on TV shows Luke Cage, The Defenders and Iron Fist. Dina Shihabi played Neda Kazemi on TV show Daredevil.
Time 22:24 Poe and Kovacs walk past a statue remarkably like Thanos. Perhaps a nod to actors marvel links.
