Mine happened off screen in a Grimiore Card, he was on the moon hunting Hive, and ran into a House Of Exile Vandal, normally he would of killed her, but both were pinned down by Hive, so for a moment, enemies became allies and worked together to kill them, iirc she got injured and before he could help her, she tried to stab him, forcing him to kill her, to spare him the choice He did call them bugs , and hated Taniks with a passion , but he wasn't a close minded idiot Second was in the reprised nexus mind strike in D1 , he told Ikora he was helping us with the Strike because he was bored , and she told him if he was bored the Warlock halls could use a mopping and he pretended like he didn't hear her And 3rd is a tie between all the brother and sister banter between him and Eris Cayde:"Get Your Rock Off My Map" Cayde:"I will keep my ear to the ground" Eris:"And I will try not to step on his head" There are hundreds of my favorite Cayde moments, there isn't any bad ones except when I had to helplessly watch him die, and the game didn't let me chase down The Barons and prince boy right there and beat them to death individually with my bare hands!

When he fights with the Colonel in the Red War cutscene.... I tried to find a good clip of it, but I couldn't.
