When Luke is found by the resistance members, graffiti on the plywood of the coffee shop he hides out in reads "God hates fags", which, aside from reflecting the generally hostile attitude of the Gileadean regime toward the LGBTQ community, is also the slogan of the Westboro Baptist Church of Topeka, Kansas, who are vehemently anti-gay.
When Luke gets the letter from June, you can see paintings of Abraham Lincoln and Benjamin Franklin at the back of the room.
A guy named Whitfford helps June and Luke try to get free. In season two Bradley Whitford joined the cast as Commander Lawrence.
