"Damnably quick pintsized Jedi pipsqueak!" Jacen called after Jaina as he initiated his own Force Speed to try to keep up with her. That was the trouble with Jaina. She was small, so she had less mass to slow her down.
Jacen rounded the corner that Jaina had been at just a moment before, running as quickly as his Force-enhanced speed allowed him to, keeping track of Jaina as much through their twin bond as through the Force itself. He'd have to severe that soon, to keep Jaina out of his secrets, but for now, he relished the feeling of being close to her. It was...intoxicating.
"Oh, now you're just showing off!" he exclaimed as he watched his sister do her take on the antics of a Kowakian monkey-lizard. Moving with considerably less grace, Jacen mimicked her ascent, moving up the building in a series of Force jumps. When he finally landed, he spotted his sister sitting on some sort of device, dangling her feet like a bored child.
"Go ahead and say it. It's on the tip of your lips."
