Comfort.
The fourth time he forms the first thing he does is wrap his arms around himself. He takes several deep breaths and closes his eyes. His initial confusion fades as he calms down. He's on a bed. Their bed. One of them must have had a nightmare.
"It's okay." Tiencha whispers to himself. "I'm here."
He stays like that for a while. The pain the nightmare had caused slowly vanished. He couldn't remember what it was or which half had it. It didn't matter. They were together now and had been for a long time. Tiencha smiled softly. His halves had definitely gotten closer then the last time he had existed and they had already been in love back then.
He opened his eyes to see an engagement ring on each hand. Simple, silver, and small enough to not draw too much attention on one hand. Must be Tien's. The other was slightly larger with a bright orange gem set in the middle. The center of attention. That was Yamcha. Tiencha grinned wider as he looked down at the rings.
"You two had better give me at least one dance at the wedding." Tiencha said. He spoke directly to his two halves. He had formed enough times to cement his own personality and opinions and his current opinion was that the big day couldn't come soon enough.
He let himself fall back into the bed and start to drift off to sleep. He knew he would run out of time and unfuse by morning for sure but for the moment he drank in the feeling of being together. A ghost of a smirk crossed his face as he finally began to sleep knowing that his halves would wake up in each others arms.
