Beast Wars Analogy ahoy!
Scene toward the end of my book, using Beast Wars characters because I find it funny:
For the purpose of this example, main character is Dinobot. Dinobot is doing some serious Dinobot-level scenery-chewing. Serious melodrama ranting.
Love interest Silverbolt is being useless and sort of chivalrous and mostly just shambling around hopelessly trying to talk Dinobot out of doing something extremely stupid and it's not very effective.
Best friend Rattrap has shown up and is like "Yeah no, I need you to knock that right the hell off what is WRONG WITH YOU"
That scene needed best friend Rattrap.
