Ho Yay: Gaysparkle and Deathstar. Ancient loves Deathstar too, but he doesn't love him back. According to Chapter 10, Phantom is in love with Deathstar. Shadowseeker flirting with Sunsetshine might count, but we really can't tell if Sunsetshine was a guy at the time.
Narm: Barely a sentence goes by without it being narm-y.
Particularly Screepaw's death.
"NO! Screepaw, my love, I will avenge your death!" Tranquila cried. Tears streamed down her face, and she collapsed to the ground by her dying lover.
"There's nothing you can do, Tranquilpaw!" the blue-gray tom said. "Take care of our kits and remember I love you forever, even when I am in StarClan!" And then Tranquilpaw kissed him one last time and then his eyes closed and then he was gone.
And the fight between Moonshimmer and Tranquildream.
""Stop it! We can not do this! I will not fight! I am a pacifier!" Screamed Moonshimmer. Her fur was prickling and her purple eyes were wide and the moon on her forehead was beginning to glow. Sometimes it did that when there was danger around her!
" Tranquildream ran towards Moonshimmer and used her elemental powers! She made weeds and vines grow out of the ground and wrap around Moonshimmer's paws! Moonshimmer struggled to get out of them and she let out a huge rainbow burst of energy that destroyed all of the vines! She looked super mad now!”
