Loki and Thor...it always bothered me that while Loki mentioned his love for Thor twice, no one ever said "I love you" to Loki, when he most needed to hear it. Odin said "You are my son, I wanted to only protect you from the truth." rather than "You are my son and I love you." I LOVE YOU LOKI DOKI DONT WORRY
What kills me is that Thor says "when". "WHEN you betray me, I will kill you." And then Loki, all sass and concentrated, convoluted, complicated emotions says, "WHEN do we start?" The layers to this rip my heart apart.
