These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Roman slips Peter a note saying "Can I watch?" — he's talking about the transformation from human to wolf, but the subtext is practically text.
In the novel, when Olivia questions what Roman and Peter were up to in Roman's room, Roman answers, "homosexual acts".
Roman also states that watching Peter transform back to human is "beautiful".
Throughout the novel, the narrator interjects with various statements that play up the Ho Yay.
Kick the Dog: From Christina to Chief Tom Sworn, when both Alexa and Alyssa are both mutilated/murdered horribly by the vargulf, considering Chief Tom Sworn was always so kind to the murderer. Made worse when later Christina is killed, but is possibly alive, as she screams from in the grave even though she was the killer, he didn't know that and he saw her as a daughter.
Narm Charm: Christina trying to become a werewolf by drinking from a muddy paw print was just silly. But silly or not, it worked.
Peter's first on-screen transformation in the TV adaptation definitely qualifies. It includes Peter's flesh being flayed off, his teeth falling out and then his wolf form proceeding to eat some of the flayed off flesh. Suffice it to say that Netflix did not skimp on the special effects.
And then there was the part where Christina (in vargulf form) ate Peter's face...
Squick: As if the vargulf eviscerating its victims wasn't bad enough, it had to go out and attack the victims by ripping apart their vaginas first.
Perhaps that's exactly why they did it. Most, if not all, of the characters killed off at that point were only there to be killed off, you never got an emotional bond with them or knew them at all. Whether you liked Chausser or not their death was a slap to the face, no one saw it coming, but considering Pryce's surprising statement we might see them again.
The Woobie: Shelley and to a lesser extent Peter. Both of them get far more hate than they deserve considering they are generally good, helpful people.
