It had been a few weeks since Robin introduced the concept of cycling patrols between the Titans. He made the point that they needed to take a more active approach to fighting crime, rather than just sit around and wait for the alarm to go off. This led to Cyborg taking the morning when he's fully charged, Starfire taking afternoons while she can take in the most sunlight, and Robin took evenings because "that's when I'm the most alert." Raven and Beast Boy were then saddled with the night shift.
It wasn't an illogical choice. They were both people who were frequently still awake while everybody was still asleep. Beast Boy's variety of animal forms meant that he could take on any nocturnal animal on the planet, and Raven could operate more subtly in the dark. Then there was the element of fear as Robin had described it. Criminals were more jumpy at night, and being face to face with a lion while trying to make off with stolen loot wasn't something criminals looked forward to. Raven herself, was the subject of multiple rumors and theories in the criminal underworld, often ending with the idea that she can eat souls. She wasn't sure what to think of the fact that she was just naturally scary.
Being forced to spend time with Beast Boy was nowhere near as bad as she made it seem. What was genuine frustration and annoyance when they were barely teenagers had since transformed into playful ribbing. Something they just did without really thinking about it. They would spend patrols going back and forth between playful jabs and making meaningful conversation. Then, they would come home in the morning, and get to sleep. Sometimes they made it to their rooms, other times they passed out on the couch and woke up to find that they cuddled each other in their sleep. That still made them a frequent target of Cyborg.
Having the same sleep schedule now meant that they were with each other more than any of the other Titans. They still had their time with the other Titans, of course, but it was limited in comparison. All the time they would spend together made them that much more at ease around each other than ever before. Soon enough, the mock insults were slowly replaced with something neither had a great deal of experience with. Awkward attempts at flirting.
Going against all preconceptions, she was the one that started it. He had been making a joke out of his recent love life, going on about failed dates and how each of them of them hadn't worked out because none of them had complimented his ears.
"You know," she hesitantly began, "I like your ears."
He blushed and tried to stammer out a response, but she was already leaving him behind. Hood up so he couldn't make out the faint blush on her cheeks. The rest of the patrol was spent making awkward small talk, and blushing after stealing glance at one another. They arrived at the tower and walked to their rooms together. Before she could walk through the door, he grabbed her by the shoulder to get her attention.
"You know," he hesitantly began, "You look good with your hood up," he then moved to lower it back down, "but you look even better with it down."
He left to go to his room, leaving Raven behind like she had left him earlier: A blushing and stammering mess.
