In "Beware My Power, Part 2," Shyir Rev reuniting with his family, with whom he's implied to have been away from for some time.
In "Razer's Edge" when Razer kisses his wife, Ilana, on the forehead and promises that he will protect her. It's the closest thing we get to Razer looking truly happy and loving for quite some time.
When Aya comes to save Razer from his replaying Nightmare Sequence torture, he reveals he knew it was fake all along. He was willing to take the torture, because it meant he got to see his lost love again.
In "Heir Apparent," Kothak was portrayed as an arrogant General Ripper who wanted to consolidate power for himself, thinking the Queen unworthy. In the end, he stood with the queen when a coup was launched, revealing that he had the planet's best interests in his mind, and he bows to her when she proves herself.
Upon seeing how distressed and angry Razer got when he had to recite the Red Lantern oath, Aya took it upon herself to create a new one for him in "Fear Itself."
"The power of the crimson red,
can lead your soul away from dread,
and heal the deepest wounds of hate,
let no one else decide your fate."
It didn't work, unfortunately, but it's the thought that counts.
Kilowog and Teela. Big guy, little kid, almost annoying levels of cute.
The floating jellyfish alien taking away Teela's spear, removing the yellow crystal that was causing her paranoia, then giving back the safe pieces and patting her on the head.
Later followed by her riding atop said alien like a pony.
Carol comes to her senses after being Brainwashed and Crazy thanks to Hal invoking their mutual love. Even more, she admits that this is way over her head, but that she understands that Hal's doing important work, and can't wait for him to come home.
The end of "In Love and War", when a reformed Ghia'ta is confronted by Queen Aga'po and her troops.
Aga'po: I am disappointed in you, Ghia'ta. You have much to learn.
Ghia'ta: No, my queen. I have much to teach.
Come the season finale, she's successfully reformed the Star Sapphires.
Kilowog hugging Aya in the end of "Invasion".
The Star Sapphires can create portals which lead the user to the one they love. When used by Razer, it sends him straight to Aya.
There's a subtle one in "Babel", where Kilowog throws Razer the Manhunter head so that he can recharge with it, implying that he now thinks of Razer as one of the Green Lanterns.
Razer and Hal ultrawarp to get back to Oa so they can find Aya. Kilowog points out that they cannot do the calculations as well as Aya, and if they get it wrong, they'll end up vaporized. They go ahead anyway, and barely escape the atmosphere of a star. When Hal is trapped on Zamaron with Atrocitus, Kilowog immediately gets on board with the idea to ultrawarp to Zamaron.
Hal and Carol watching each other's backs in the fight with Atrocitus.
Razer still has faith that Aya is just malfunctioning and can be repaired, as does Hal.
Even after everything she's said and done Aya still stopped and hesitated to kill the Zamarons in Razer's presence, instead opting to leave and think out a different method that didn't involve killing him face-to-face. It shows that somewhere, deep down inside, Aya still cares about him.
"I was a monster, and you rescued me."note Hal's opinion on whether or not Aya can be saved.
When Hal is fighting off the Orange Lantern's influence.
Hal: I have a mission... can't let this battery interfere... can't turn my back on friends... can't leave the job undone.
So many in the finale, specifically the final scene in the series with Razer flying off into space in search of Aya and a Blue Lantern ring following right behind.
Tomar-Re reassuring Hal that what Aya has done is not his fault when he catches him looking at all the star systems she destroyed.
Razer referring to Kilowog as "my friend", followed by Kilowog hugging Razer as they go their separate ways.
Razer explaining how he could never kill Aya. Red Lantern constructs are powered by hate, and there could never be any hate in his heart for her, only love.
Aya and Razer's last words to each other are both sad and heartwarming.
Razer: Please, Aya, don't do this; don't leave me alone. Aya: You will never be alone. You have a family now. And somehow, I will be with you too, watching over you. Always. Razer: I don't understand. Aya: I do not either. It is just a feeling.
Razer and Hal at the end.
Hal: You get in any trouble out there, find yourself in a jam, you don't hesitate to call us. Because we will high-tail it out there and —
