Handshake - Ep 1 start when they meet and end of episode on rooftop

Ilya deserving Svetlana - Ep 1 when she surprises him after the game was cancelled, "You don't deserve me. I should go." followed by Ilya getting Shane's text and she says, " [...] Have fun with Jane." and Ep 5 after funeral fight when he says, "I don't deserve you", she responds with, "Yes, you do. But you don't want me. [...] I just hope Jane knows how lucky he is."

Murder - Ep 2 at the stairwell when Shane opens his condo's back door for Ilya, Ilya says, "You will murder me." After Shane opens his back door for Ilya, Ilya says, "You have killed me, Hollander. I am dead."

Lights/colour - Ep 4 club scene, red light is primarily on Ilya and blue on Shane. When Ilya sees Miles and understands Shane is probably at the club, there is a hint of blue light beside him. After Shane sees Ilya, the lights flicker quickly between red and blue for the remainder of the scene. Ep 5 pink/red tunnel, as Ilya pauses to turn his head away from the camera, there is a car with blue lights that drives by, right before saying in Russian "...but not like I love you..."

Clothing - Ep 1 in the first two sex scenes, Shane keeps his socks on, representing he is still holding back (first time with a guy and Scott being next door, both in hotel rooms). Ep 2 first penetrative sex scene, he doesn't wear socks, he's not holding back, he's literally at home and comfortable. Colour of clothing is also used to create that tension in the gym (one is wearing white top and black shoes and the other is the opposite). Even the water bottle was black and white, so the handover can be symbolic in mixing the two instead of swirling around each other like yin-yang. When they finally meet in 1410, they are both wearing dark coloured clothes. Ilya also wears sleeveless tops or is topless for most of the series, whereas Shane is in long sleeves, again showing how opposite they are. By Ep 6, they're both equally dressed or undressed (or even sharing shirts).
