Angry and jealous. Oh, is Nebula a Four! All of the hurt she’s suffered, physically and emotionally, have left her wide open to more pain. She doesn’t armor up like most people would. She attacks, yes, but deep inside she hopes for love. The more vulnerable she feels, the harder she hits.
She’s portrayed so beautifully, so accurately, that I really have nothing more to say. Gillan leaves it all on the screen for everyone to see.
