After Terra had left the titans permanently; Beast Boy thought he'd never be happy again. His brain always hurt from thinking too much, his body stayed numb because he never moved it, and his heart had been broken. She literally broke his heart in half.
But as he watched Raven make her daily herbal tea, he realized something. Raven had always been there for him; even when it didn't seem that way. She may not have laughed at any of his jokes, or ever agreed with him, but at least she listened. She teased him and occasionally yelled, but he knew her intentions meant well. The other titans have even admitted that they sometimes tuned him out. Plus, she never really liked Terra like everyone else did. If he had listened to Raven in the first place, all of this hurt could have been avoided.
Raven had shown affection towards him a few times; but they were just one armed hugs and the occasional smile. She just wasn't a touchy feely person. She was so mysterious; leaving you to never know what might happen next. But that was his favorite thing about her. And the fact she could kick anybody's butt... including his own.
Of course, she had her days when she basically cussed him out. But her dad was an evil demon that tried taking over the world so she had an excuse to be mad sometimes.
He felt bad that he was always getting on her nerves, but he honestly couldn't help it. She did tend to get mad easily. Like the time they threw a birthday party for her; how were ANY of the titans supposed to know that the end of the world was that day? But then again, he had called the girl creepy. If she really wanted to, she could have beamed him to another dimension right then and there. Maybe she should have. His shoulders slowly fell.
Beast Boy figured he'd never know how she would react if he never tried anything. So when she took the last sip of her tea and sat the cup down, he ran up hugged her as tight as his little green arms could. He slowly rested his head onto her shoulder, which made him feel entirely safe from anything that could ever harm him.
Raven was startled and she hugged back awkwardly. After a couple seconds of hugging, Beast Boy pulled away and blushed. Raven just smiled slightly and walked out of the room. Beast Boy grinned to himself... she wasn't that bad after all.
